Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness, weight capacity up to 250 pounds, and mounting surface suitability.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces for the selected mounting configuration (regular, top jamb, or parallel arm).
  3. Prepare door and frame by drilling required holes using appropriate fasteners including sleeve nuts & bolts, thru-bolt grommet nuts, or Torx fasteners as specified.
  4. Install mounting hardware and secure the closer to door and frame per manufacturer torque specifications, ensuring proper alignment for 2-1/8" projection clearance.
  5. Adjust spring size setting (1-6) based on door weight and application requirements, then fine-tune latch, sweep, and backcheck valves for optimal operation.
  6. Test door operation through full 180-degree swing range and verify proper closing speed, latching force, and backcheck function. Refer to manufacturer documentation for complete installation details and valve adjustment procedures.

Norton Rixson 8501A 694 – Frequently Asked Questions

1) Do I need to order a left hand or right hand version of the Norton 8501A door closer?
No handing to specify. The 8501A is a non-handed closer, and the same unit mounts push side or pull side. One part number covers both swings, which is why it is a common choice when a property manager is stocking spares for a building with doors swinging both ways.
2) What is tri-mount on the Norton 8501A, and does it cover parallel arm installs?
Tri-mount means one carton covers all three surface configurations: regular arm on the pull side, top jamb on the frame face, and parallel arm on the push side. The bracket and hardware for parallel arm come in the box, so you decide the mounting at the door rather than at the order form. That is what makes it useful for a contractor doing a mixed set of openings off one purchase.
3) Is the Norton Rixson 8501A closer ADA compliant and can it go on a fire rated door?
Both are covered. The 8501A carries ANSI/BHMA A156.4 Grade 1, is ADA compliant, and holds a UL 10C fire rating up to 3 hours. For an institutional spec sheet calling for a Grade 1 barrier free closer on a labeled opening, it meets the line. Adjust the spring size down as needed to hit the opening force limit your inspector measures.
4) Which door closer should I use instead of the Norton Rixson 8501A on a heavy traffic exterior opening?
The 8501A is rated medium duty for moderate traffic. When the opening is heavier than that, the heavy duty Grade 1 closers in the set are the ones to move to: Falcon SC71A in the SC70A series, Sargent 1431 Powerglide, Sargent 281 Powerglide with a cast iron body, BEST HD8000, and BEST EHD9000, which carries adjustable spring sizes 1-6 the same way the 8501A does. Dormakaba 8616 with the flat arm is another heavy duty Grade 1 option and ships tri-pack, so it covers multiple mountings like the 8501A tri-mount package.
5) What is the closest Grade 1 medium duty surface closer to the Norton Rixson 8501A from another brand?
The Sargent 1131 is the nearest match on the two specs that usually decide a substitution: it is a Grade 1 surface door closer rated medium duty, the same grade and duty level the 8501A carries. The Sargent 1331 is a second option at Grade 1 medium duty, described as a universal aluminum body closer, which lines up with the 8501A cast aluminum body. Falcon SC81A is a third, a medium duty Grade 1 surface-mount cast aluminum closer in the SC80A series. All three sit at the same grade and duty point as the 8501A, so the remaining checks are arm type, mounting, and finish.
6) Which alternatives to the Norton Rixson 8501A also cover regular, top jamb, and parallel arm mounting in one package?
The 8501A tri-mount package covers regular, top jamb, and parallel arm from one carton. Dexter matches that description across four Grade 1 series: DCH1000 tri mount with full cover, DCH4000, DCL2000, and DCM1000, each listed as tri mount for regular, parallel, or top jamb mounting. Accentra 2701 is a tri-pack architectural closer with adjustable spring sizes 1-6, the same spring range as the 8501A, on a non-hold-open arm. Design Hardware 316 is a tri-packed non-hold-open closer supplied with a cover, rated medium to heavy duty.
7) What looks like a substitute for the Norton Rixson 8501A but will not mount the same way?
Two things in the closer aisle read as alternatives and are not drop-in for a tri-mount surface closer. Corbin Russwin DC5230 is a Grade 1 surface closer, but its standard arm is a slide track arm and it is specified pull side mounting, so it prepares the frame differently from a tri-mount regular, top jamb, or parallel arm installation. Dorma 8916-JT is a Grade 1 closer with a jamb track and frame face mounting, pull side only, in spring size 1-6. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting bracket rather than a closer. Stanley 327 and 341 are wardrobe pivots, not closers at all.
8) The spec on the drawing calls for Grade 1 - which door closers should I not offer against the Norton Rixson 8501A?
The 8501A carries ANSI/BHMA A156.4 Grade 1. Two closers in the comparable set sit below that: the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, and the Falcon SC91A is Grade 3 light duty. Both are surface closers and will physically do the job on a light interior opening, but neither meets a Grade 1 line item. If the drawing calls Grade 1, the Cal-Royal 500S, Cal-Royal 700S, Corbin Russwin DC3200, and Sargent 1131 are all Grade 1 surface closers in the same aisle.
9) How much clearance does the Norton 8501A door closer need off the door face?
Projection is 2-1/8 inches. That is the dimension to check against anything close to the top of the door: a transom mullion, a soffit above the frame, a card reader housing, or a door that swings back tight against a wall. The closer also allows a full 180 degree swing where the opening permits it.
10) Can I adjust closing speed and latch separately on the Norton 8501A?
Yes, three independent valves: latch speed, sweep speed, and backcheck intensity, each adjusted on its own. Backcheck is the one that saves the door in a windy vestibule, it cushions the swing before the leaf hits the wall. The valves are staked so they cannot be backed out accidentally, which matters on doors the public can reach.
11) What is a good equivalent to the Norton 8501A door closer from another brand?
For a Grade 1 medium duty surface closer with the same tri-pack flexibility, the closest cross-brand matches are the Falcon SC81A Series, the Sargent 1331 with its universal aluminum body, the BEST HD7000 Series, and the Dexter DCH4000 Series tri-mount. All are Grade 1 surface closers. The Sargent 1131 is another medium duty Grade 1 option in the same class.
12) I only need a closer on a light interior office door, is the 8501A overkill?
For a light interior door the size 1-6 range and 250 pound capacity of the 8501A is more closer than the opening needs. Lighter Grade 1 options include the BEST SL6000 Series, the Arrow DCN314 with spring sizes 1-4, and the Falcon SC61A light to medium duty. The LCN 1250 Series covers sizes 1-5 in a light duty ADA compliant unit. Where the door is heavy or the opening is exterior, come back to the 8501A.
13) Should I use a surface closer like the Norton 8501A or a slide track closer?
An exposed arm closer like the 8501A pushes the door with a lever arm that stands off the face, needing 2-1/8 inches of projection, and it gives you a strong backcheck for wind loaded doors. A slide track closer tucks the arm into a track on the frame for a cleaner look and less vandal exposure, at some cost in power. If the architect wants the track look, the Corbin Russwin DC5230 Series is a Grade 1 slide track arm closer for pull side mounting. On a service door or anywhere power matters more than appearance, stay with the exposed arm.
14) What is a hold open alternative to the Norton Rixson 8501A?
The 8501A offers a hold open feature. If you want a closer that arrives configured with a hold open arm, the Accentra 51 Series is an industrial closer with hold open, tri-packed mount options, and spring size 1-6, which lines up with the 8501A tri-mount coverage and 1-6 spring range. Orca BHDC1958HO ships a tri-packed hold open arm for 1-3/4 inch doors. Stanley A45-501HL uses a long hold open arm, top jamb mounted, which is one of the three mountings the 8501A tri-mount package covers.
15) Is there a lighter duty closer than the Norton Rixson 8501A for an interior office door?
Yes. The 8501A is medium duty; for lighter interior openings the set includes several light duty Grade 1 closers. Arrow DCN325 is a Grade 1 surface closer with adjustable spring size 1-6 and regular/parallel arm tri-pack, the same spring range as the 8501A. Arrow DCN314 is the same family limited to spring size 1-4. BEST SL6000 is a light duty Grade 1 closer with adjustable spring sizes, and LCN 1250 is a light duty closer in sizes 1-5 with all-weather fluid and ADA compliance, matching the 8501A on ADA. Falcon SC91A is light duty but Grade 3 rather than Grade 1, so check that against your spec.
16) For a facility standardizing on Grade 1 closers, which brands besides Norton Rixson carry a Grade 1 surface closer with an adjustable size 1-6 spring?
The 8501A uses an adjustable size 1-6 spring at Grade 1. Others in the set with both the Grade 1 rating and a stated 1-6 adjustable spring are BEST EHD9000, Dorma 8916-JT, and Arrow DCN325. Accentra 2701 and Accentra 51 Series also list spring sizes 1-6 on tri-pack mounting. Imperial USA TC4300 is a heavy duty size 1-6 ADA closer. Calibre CA9901 is a Grade 1 tri-pack ADA surface closer covering spring sizes 2-5, a narrower range than the 8501A.
17) Does the Norton Rixson 8501A come with a cover, and which comparable closers state their cover arrangement?
The 8501A is available with slim line and full cover options, and it is pictured with an architectural plastic cover. Among comparables, Dexter DCH1000 is a Grade 1 tri mount closer specified with a full cover, and Design Hardware 316 is supplied with a cover. On the other side, Arrow DCN314 and DCN325 are both Grade 1 tri-pack closers supplied less cover, so a cover has to be handled separately if the opening calls for a finished appearance.
18) I need a delayed action closer rather than the Norton Rixson 8501A - what is available?
The 8501A uses separate latch, sweep, and backcheck intensity valves. For an opening that needs a delayed action function, the Orca BHDC1958DA and BHDC2011DA are delayed action closers with a regular arm and parallel bracket, both listed for 1-3/4 inch doors and supplied as tri-packed non-hold-open arms. The tri-pack arrangement covers multiple mountings the way the 8501A tri-mount package does. The Orca BHDC1958RA is the same series with a standard regular arm if delayed action is not needed.
19) Which alternatives to the Norton Rixson 8501A use a cast iron body instead of cast aluminum?
The 8501A has a cast aluminum body. If your standard calls for cast iron, the Sargent 281 Powerglide is a heavy duty Grade 1 surface closer with cast iron construction, and the LCN 1261 is a cast iron closer with adjustable spring sizes 1-5, rated light to medium duty. For staying with aluminum, the Sargent 1331 uses a universal aluminum body at Grade 1 medium duty and the LCN 1450 is a medium duty cast aluminum closer with spring sizes 1-6, the same spring range as the 8501A.
20) Are there ADA barrier free closers comparable to the Norton Rixson 8501A?
The 8501A is ADA compliant at Grade 1. Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check, matching the 8501A on both the Grade 1 rating and independent backcheck control. Cal-Royal N900PBF is a barrier free Grade 1 hydraulic surface closer in the 900 series. Calibre CA4001 is a Grade 1 hydraulic closer with adjustable spring tension for ADA, and Calibre CA8001P is a Grade 1 ADA surface closer in a parallel arm size 1 configuration, one of the three mountings the 8501A tri-mount package covers.
21) What cover comes on the Norton 8501A and can I get a metal one?
Cover choice runs slim line and full. The standard shipping cover is architectural plastic, which is what most commercial installs get. Finishes offered are 613E dark oxidized satin bronze, 689 aluminum, 690 dark bronze, 691 light bronze, 693 flat black, 694 medium bronze, and 696 satin brass painted, so you can match the closer to existing door hardware across a building.
22) How long will a Norton 8501A closer last on a busy office door?
The 8501A exceeds 25 million cycles, with a cast aluminum body and a 1-1/4 inch diameter piston. For an office or school corridor door cycling all day, that is the number worth comparing against, and it is why the closer stays serviceable long after the arm finish wears.
23) What fasteners do I need to mount the Norton 8501A on a hollow metal or wood door?
Mounting hardware runs to sleeve nuts and bolts, thru bolt grommet nuts, or Torx fasteners depending on the door construction and how much security the opening needs. Thru bolting is the usual call on a wood or hollow core door where sheet metal screws will not hold under spring load. Templates for regular, top jamb, and parallel arm layouts come with the closer.
