Parts & Accessories
Norton Rixson 8501-690 – Frequently Asked Questions
1) Will the Norton Rixson 8501 closer handle a heavy exterior storefront door?
The 8501 handles doors up to 250 lbs, with spring power adjustable across sizes 1 through 6, so one closer covers everything from a light interior door to a wide heavy exterior opening. Cast aluminum body with a 1-1/4 inch piston, and it's rated for both interior and exterior use. Set the spring size to the door weight and width during install, then dial in latch, sweep and backcheck on the separate staked valves. One caution on duty: it's classed medium duty and rated for moderate traffic, so on a constantly cycled main entrance a heavy duty closer is the better call.
2) Do I have to order a left hand or right hand Norton Rixson 8501 door closer?
No handing to specify. The 8501 is non-handed, so the same closer works on a left or right hand door. What you do have to decide is the mounting: regular arm on the pull side, parallel arm on the push side, or top jamb on the frame face. The arm option you pick locks that in, and several of the arm choices are mount-specific (top jamb only, parallel arm only, pull side slide track, push side slide track), so pick the arm to match the side of the door you can mount on.
3) Is the Norton Rixson 8501 closer fire rated and can it go on a labeled door?
Fire rated, yes. The 8501 is UL 10C positive pressure tested and UL-cUL fire rated up to 3 hours, and it's ANSI/BHMA A156.4 Grade 1 certified. For a labeled opening, order a non-hold-open arm, since a mechanical hold open defeats the self-closing function a fire door assembly requires. Hold open arms are offered on the 8501 and belong on non-rated openings, or paired with separate electromagnetic hold-open hardware tied to the alarm.
4) Can I get a Norton Rixson 8501 with delayed action for an accessible or hospital door?
Delayed action is an ordering option on the 8501, selected yes or no when you configure it. It holds the door near open for a few seconds before the sweep begins, which is what you want on doors used by wheelchair users, gurneys, or carts. The closer is ADA compliant in operation, and separate staked valves for latch, sweep and backcheck let you set the closing force where the code requires it. The staking is tamper resistant, so the valves don't drift out of adjustment from casual fiddling.
5) What is the closest equivalent to a Norton Rixson 8501 if I need to standardize a building on one closer?
For a straight swap in the same class, the Sargent 1331 and 1131 are Grade 1 medium duty surface closers with an aluminum body, the BEST HD7000 Series is Grade 1 medium duty, the Falcon SC81A is a medium duty cast aluminum surface closer, and the LCN 1450 Series is medium duty cast aluminum with spring sizes 1-6. The Dormakaba 7303 and 7414 are also Grade 1 medium duty. Like the 8501, several of these are tri-pack closers, so one part number covers regular, parallel and top jamb mounting across a whole building.
6) What is the closest Grade 1 medium duty surface closer to the Norton Rixson 8501 if I need to match an existing spec with a different brand?
The Norton Rixson 8501 is a Grade 1 medium duty surface mounted closer. Two peers sit at the same grade and duty level: the Sargent 1331, a Grade 1 medium duty surface closer with a universal aluminum body, and the Falcon SC81A, a Grade 1 medium duty cast aluminum surface closer. The BEST HD7000 is also Grade 1 medium duty, with adjustable spring power and backcheck control. All three carry the same grade and duty classification as the 8501, so a Grade 1 medium duty line item on a drawing can be satisfied by any of them.
7) The door is heavier than the 8501 is rated for. What surface closer should I use instead?
The Norton Rixson 8501 is rated for doors up to 250 lbs at medium duty. For an opening past that, step to a heavy duty Grade 1 body. The BEST EHD9000 is an extra heavy duty Grade 1 surface closer with adjustable spring sizes 1-6, matching the 8501 spring range at a higher duty class. The Sargent 1431 Powerglide and the Falcon SC71A are both Grade 1 heavy duty surface closers, and the Sargent 281 Powerglide is a Grade 1 heavy duty closer with a cast iron body rather than aluminum. The Design Hardware 416 is a heavy duty closer supplied as a tri-packed non-hold-open arm.
8) I need a Grade 1 closer with a slide track pull side arm. What are my options besides the Norton Rixson 8501?
The Norton Rixson 8501 offers pull side slide track, push side slide track, and top jamb pull side slide track arms in both hold open and non-hold open. If the specification calls out a different manufacturer, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard for pull side mounting on 1-3/4 inch doors, and the Dorma 8916-JT is a Grade 1 heavy duty jamb track closer for frame face pull side mounting with adjustable size 1-6 and a flat non-hold-open arm. Both are track applications rather than projecting arm applications, so the head clearance and frame face prep differ from a regular arm closer.
9) I want the same tri-mount flexibility as the Norton Rixson 8501 but from a different manufacturer. What matches?
The Norton Rixson 8501 is non-handed and mounts regular, parallel or top jamb from the same body. The Dexter DCH1000 is a Grade 1 surface closer with tri mount for regular, parallel or top jamb mounting and a full cover, which is the closest match including the cover. The Dexter DCH4000, DCL2000 and DCM1000 are Grade 1 tri mount surface closers as well. On the Arrow side, the DCN325 is a Grade 1 surface closer with a regular and parallel arm tri-pack and adjustable spring size 1-6 supplied less cover, while the DCN314 is the same arrangement with spring size 1-4.
10) I need a delayed action closer. Does the Norton Rixson 8501 do that, and what else does?
The Norton Rixson 8501 is ordered with delayed action as a yes or no selection, so the feature comes from the 8501 body itself rather than from a separate series. Among comparable products, delayed action is a series-level split: the Orca Hardware BHDC1958DA is a delayed action closer with a regular arm and parallel bracket for 1-3/4 inch doors, and the BHDC2011DA is the same delayed action arrangement in the 2011 series, while the BHDC1958RA is the standard non-delayed regular arm version and the BHDC1958HO is the hold open version. On the 8501, delayed action and hold open are independent choices.
11) For a barrier free or ADA opening, what are the alternatives to the Norton Rixson 8501?
The Norton Rixson 8501 meets ADA requirements and adjusts through spring sizes 1-6 to tune opening force. The Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check, and the Cal-Royal N900PBF is a Grade 1 barrier free hydraulic surface closer in the 900 series. The Calibre CA4001 is a Grade 1 adjustable spring tension ADA hydraulic closer, the CA9901 is a Grade 1 ADA surface mount closer with a tri-pack arm in size 2-5, and the Imperial USA TC4300 is a heavy duty ADA closer in size 1-6. Note the CA9901 starts at size 2, so it does not reach the size 1 setting the 8501 provides for the lightest openings.
12) What hold open closers can I use in place of the Norton Rixson 8501 hold open versions?
The Norton Rixson 8501 offers hold open in a wide arm range, including CloserPlus, CloserPlus Ramp, CloserPlus Spring, parallel rigid, Unitrol parallel and Unitrol top jamb, and slide track arms. For a hold open unit from another manufacturer, the Accentra 51 Series is a tri-packed hold open closer in size 1-6, matching the 8501 spring range, and the Orca BHDC1958HO is a tri-packed hold open closer with a parallel bracket for 1-3/4 inch doors. The Stanley Security A45-501HL is a top jamb unit with a long hold open arm standard, which suits a top jamb condition specifically rather than a tri-mount application.
13) I need a door closer that won't get pulled off the door in a school corridor. What Norton Rixson 8501 arm should I use?
For abuse-prone openings, go to a rigid or Unitrol arm rather than the standard forged arm. The 8501 offers a parallel rigid arm and a regular rigid arm, and Unitrol parallel and top jamb arms, which add a stop function to hold the door back from a wall or from wind catch. A slide track arm, push or pull side, is the other approach: it keeps the arm tight to the door with nothing to grab, which is why it's common in schools and psychiatric or detention areas. All are offered hold open or non-hold-open.
14) Do sex nuts and bolts come with the Norton Rixson 8501, or do I order them separately?
Sex nuts and bolts are a separate selection when ordering the 8501, included or not included. Order them included when you're mounting on an aluminum or hollow metal door that can't be reliably tapped, or on a wood door where you want the closer thru-bolted so it can't tear out under repeated pulls. If the door is already prepped and tapped, the standard machine screws are enough. Thru-bolt grommet nuts and Torx fasteners are the other mounting options for the install.
15) What's the difference between the Norton Rixson 8501 and a heavy duty closer like the BEST HD8000 or Falcon SC71A?
Duty class is the difference. The 8501 is a medium duty, Grade 1 closer rated for moderate traffic, which suits offices, classrooms, retail and multi-family corridors. For a main entrance or a high-abuse opening cycling all day, the heavy duty peers are the better match: the BEST HD8000 and EHD9000 Series, the Falcon SC71A, and the Sargent 1431 Powerglide are all Grade 1 heavy duty. If the opening is lighter than the 8501 needs, the Falcon SC61A is light to medium duty Grade 1 and the LCN 1250 Series is light duty.
16) Is the Norton Rixson 8501 good enough for a spec that calls for Grade 1 and high cycle life?
It meets a Grade 1 call. The 8501 is certified to ANSI/BHMA A156.4 Grade 1 and tested past 25 million cycles, with UL 10C positive pressure and UL-cUL fire ratings up to 3 hours. That covers the usual institutional spec language on grade, cycle life and fire. Where it can miss a spec is duty class: it is a medium duty closer, so if the drawing calls out heavy duty specifically, substitute rather than argue the grade.
17) Which Norton Rixson 8501 arm holds the door open, and where should I not use one?
Hold open is available across most of the 8501 arm range: CloserPlus, CloserPlus Spring, CloserPlus Ramp, parallel rigid, pull and push side slide track, low profile slide track, the tri-style regular/parallel/top jamb arm, and both Unitrol arms. The hold open point is set at install. Keep them off fire-rated openings, stair doors, and smoke barriers, where the door has to close and latch on its own. For a loading door or a classroom that needs to be propped in daylight hours, hold open is the right call.
18) The door has a narrow top rail and the closer won't fit. Can I still use a Norton Rixson 8501?
Usually yes, with a plate. The 8500 Series drop plates lower the closer body onto the door face when the top rail is too shallow for the standard mounting pattern, and the decorative back plate covers the prep from an earlier closer that doesn't line up. A parallel arm mount with a drop plate is the common fix on an aluminum storefront door with a narrow rail. Measure the available rail height against the closer footprint before ordering the plate.
19) Is there a lighter or simpler closer than the Norton Rixson 8501 for a low-traffic interior door?
The Norton Rixson 8501 is a medium duty, moderate traffic closer with spring sizes 1-6 and independent latch, sweep and backcheck valves. For an interior door that does not need that range, the BEST SL6000 is a Grade 1 light duty surface closer with adjustable spring sizes, and the Arrow DC314 is a Grade 1 light duty surface closer in the DC300 series. The LCN 1250 is a light duty closer with sizes 1-5 and all-weather fluid. The Falcon SC91A is light duty at Grade 3 rather than Grade 1, so confirm the opening does not carry a Grade 1 requirement before substituting it.
20) What is the difference between the Norton Rixson 8501 and an Accentra tri-packed closer?
The Norton Rixson 8501 is a Grade 1 medium duty closer with adjustable spring sizes 1-6 and a 250 lb door capacity, supplied non-handed for regular, parallel or top jamb mounting. The Accentra 2701 is a tri-packed non-hold-open arm closer with adjustable spring sizes 1-6, and the Accentra 51 Series is a tri-packed hold open closer in size 1-6. The Accentra 1101BF is also tri-packed non-hold-open but adjusts only through spring sizes 1-4, so it covers a narrower door width and weight range than the 8501. On the 8501 the hold open decision is made by arm selection rather than by moving to a different series.
21) Which closers look like a substitute for the Norton Rixson 8501 but are not?
Three items in the surface closer aisle will not stand in for a Norton Rixson 8501, a Grade 1 surface mounted closer. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer body. The Stanley Security 327 and 341 are wardrobe pivots, hanging hardware for 1-3/8 and 1-3/4 inch and 1-1/8 to 1-3/8 inch doors respectively, and they do not control closing at all. The Cal-Royal 400 Series is a hydraulic commercial closer but is Grade 2, so it does not carry the 8501 Grade 1 classification if the spec requires it.
22) I am standardizing a facility on one closer. What Grade 1 lines cover the same range as the Norton Rixson 8501 across light, medium and heavy openings?
The Norton Rixson 8501 covers spring sizes 1-6 up to 250 lbs in a single Grade 1 medium duty body, so one part number spans a range of openings. If the standard has to be a different manufacturer, BEST and Falcon each offer a Grade 1 ladder: BEST runs the SL6000 light duty, HD7000 medium duty, HD8000 heavy duty and EHD9000 extra heavy duty; Falcon runs the SC61A light to medium duty, SC81A medium duty and SC71A heavy duty, all Grade 1. Sargent covers medium duty with the 1131 and 1331 and heavy duty with the 1431, all Grade 1.
23) The 8501 with a full cover projects too far off the door. What is a lower profile alternative?
The Norton Rixson 8501 has a 2-1/8 inch projection with a full cover, and is also available with low profile arms in regular, parallel, push side slide track and pull side slide track versions, plus slim line cover. If a flatter arm from another manufacturer is wanted, the Dormakaba 8616 AF86P FC is a Grade 1 heavy duty closer with a flat non-hold-open arm supplied as a tri-pack with a full cover, and the Dorma 8916-JT is a Grade 1 heavy duty jamb track unit with a flat non-hold-open arm. Flat arm and track arm designs change the arm geometry, not the closer body depth, so confirm the head condition before switching.
24) Which alternatives to the Norton Rixson 8501 are stated for 1-3/4 inch doors?
Several Grade 1 peers are specified at a 1-3/4 inch door thickness: the Corbin Russwin DC3200 with a regular arm, the DC5230 with a slide track pull side arm, and the DC6200 and DC8200, both double lever regular arm pull side mounted closers. The Orca Hardware BHDC1958 series is also stated at 1-3/4 inch, in regular arm, hold open and delayed action versions with a parallel bracket. That thickness is the common commercial door leaf, so any of these drops onto a standard hollow metal or wood commercial door without special prep.
25) Is the Design Hardware 316 a reasonable stand-in for the Norton Rixson 8501?
The Norton Rixson 8501 is a medium duty closer supplied non-handed for regular, parallel or top jamb mounting, with both hold open and non-hold open arms available. The Design Hardware 316 is a medium to heavy duty closer furnished with a cover and a tri-packed non-hold-open arm, so it spans the 8501 duty level and carries the same tri-pack mounting flexibility. The one behavioral difference to check is hold open: the 316 is stated with a non-hold-open arm, and the heavier Design Hardware 116 and 416 are the same. If the opening needs mechanical hold open, that is a function the 8501 arm selection provides directly.
26) What finishes does the Norton Rixson 8501 door closer come in, and can I match dark bronze storefront?
Nine finishes on the 8501: 689 aluminum, 690 dark bronze, 691 light bronze, 694 medium bronze, 613E dark oxidized satin bronze, 693 flat black, 696 satin brass painted, plus BSP black suede powder and WSP white suede powder. For dark bronze anodized storefront, 690 is the usual match; 613E is the darker oxidized bronze used when the rest of the door hardware is a living-finish bronze. The suede powder finishes are the more durable coating for exterior exposure.
