Norton Rixson UNIJ7500-690-5-1/2-REVEAL – Frequently Asked Questions

1) Does the 7500 Series closer hold the door open?
No. The 7500 Series is a non-hold-open closer, so the door returns and latches every cycle. If someone needs a door to stay open at a set angle, that is a different arm entirely: the Accentra 51 Series and the Orca BHDC1958 hold-open version are both catalogued with a hold-open arm. On a fire-rated opening a hold-open closer is normally the wrong choice anyway, since the door has to self-close.
2) What does top jamb parallel arm mounting mean, and when do I need it instead of a regular arm closer?
Top jamb mounting puts the closer body on the frame face above the door rather than on the door leaf, with the arm reaching back to the door. It is what you use when the door itself has no room for a closer or when the closer has to sit on the push side, which is the usual case on out-swinging exterior doors. Regular arm mounting, like the Corbin Russwin DC3200 or the Dexter DCL2000, puts the body on the pull side of the door instead. The Unitrol arm on the 7500 combines the closer arm with a stop function, so it controls the door at the open position instead of relying on a separate floor or wall stop, which is what you want on a wind-exposed opening.
3) What is the closest heavy-duty Grade 1 surface closer to the Norton Rixson 7500 Series if the 7500 is not the right fit?
The Norton Rixson 7500 Series is a heavy duty, ANSI/BHMA A156.4 Grade 1 surface mounted closer. Two peers match on both counts: the BEST HD8000 Series is a heavy duty Grade 1 surface mounted closer, and the Falcon SC71A Series is a heavy-duty Grade 1 surface-mount closer. The Sargent 1431 Powerglide is also heavy duty Grade 1 with adjustable spring power, which lines up with the 7500's adjustable spring sizing.
4) Which door closer should I use on a lighter interior door instead of the Norton Rixson 7500?
The Norton Rixson 7500 Series is built as a heavy duty closer for high traffic openings carrying doors up to 250 lbs. For a lighter interior opening, the BEST HD7000 Series is a medium duty Grade 1 surface mounted closer, the Falcon SC81A Series is a medium duty Grade 1 cast aluminum surface-mount closer, and the BEST SL6000 Series is a light duty Grade 1 surface mounted closer with adjustable spring sizes. All three hold the same Grade 1 rating as the 7500 at a lower duty level.
5) I need a hold open arm on the opening - what closer do I use instead of the Norton Rixson 7500?
The Norton Rixson 7500 Series does not offer a hold open feature. For an opening that has to stand open, the Accentra 51 Series is an industrial closer with a tri-packed hold open arm in sizes 1-6, the Orca Hardware BHDC1958HO/PA is a hold open closer with a tri-packed hold open arm and parallel bracket, and the Stanley Security A45-501HL is a long hold open arm standard, top jamb configuration.
6) What are the alternatives to the Norton Rixson 7500 for a top jamb mounted closer?
The Norton Rixson 7500 Series is configured with a top jamb Unitrol parallel arm. Peers that cover top jamb mounting include the Dexter DCH1000 Series, a Grade 1 surface closer with tri mount for regular, parallel or top jamb mounting and a full cover, and the Dexter DCH4000 Series, a Grade 1 tri mount surface closer in the same three configurations. The Dorma 8916-JT is a Grade 1 heavy duty jamb track closer for frame face mounting on the pull side, adjustable size 1-6.
7) Do I have to order a specific spring size for my door, or is the 7500 closer adjustable?
Spring power is adjustable on the closer, so one unit covers a range of door sizes instead of forcing a size decision at the order stage. That matters for a property manager buying for a mixed set of openings: the same closer goes on a heavier entry and a lighter interior door, and the tech dials in the power on site. Closing speed, backcheck, and latching speed are separately adjustable at the valves.
8) What is the difference between the Norton Rixson 7500 and a lighter closer like the LCN 1250 or Arrow DC314?
Duty level is the split. The 7500 Series is a heavy-duty Grade 1 closer built for high-traffic openings and doors to 250 lbs. The LCN 1250 Series and the Arrow DC314 are both catalogued as light duty, which suits interior office and residential-corridor doors that see moderate use. If the door is an exterior entrance, a stairwell, or a main corridor in a school, the heavy-duty body is the one that survives; on a low-use closet or utility door a light-duty closer is the sensible spend.
9) What other heavy-duty Grade 1 surface closers could I use if I need a different mounting or brand?
Several heavy-duty Grade 1 surface closers sit in the same class. The BEST HD8000 Series and EHD9000 Series are both heavy-duty Grade 1. The Falcon SC71A and the Sargent 1431 Powerglide are heavy-duty Grade 1 as well. If the opening needs tri-pack flexibility so the installer can decide regular, parallel, or top jamb mounting in the field, the Dexter DCH1000 and DCL2000 are Grade 1 tri-mount closers. Where a hold-open or delayed-action arm is required, that changes the product rather than the mounting, since the 7500 is non-hold-open.
10) Will the 7500 closer meet ADA opening force requirements on an accessible entrance?
Closing speed, backcheck, and latching are all adjustable on the 7500 Series, which is what lets a tech tune the closer to the opening force and closing time an accessible opening calls for. On an exterior door the practical limit is usually the door weight and wind, not the closer, and the adjustable spring power gives room to set the lowest force that still closes and latches the door reliably.
11) Which heavy-duty closers can I standardize on across a facility alongside the Norton Rixson 7500?
The Norton Rixson 7500 Series is a heavy duty Grade 1 surface mounted closer with adjustable size springs. Peers at the same heavy duty level include the BEST EHD9000 Series, an extra heavy-duty Grade 1 surface mounted closer with adjustable spring sizes 1-6, the Sargent 281 Powerglide cast iron heavy-duty closer at Grade 1, the LCN 1460T heavy duty Grade 1 commercial closer in a powder coat finish, and the Imperial USA TC4300 Series, a heavy duty Grade 1 size 1-6 ADA closer. Design Hardware 116 and 416 Series are heavy duty closers supplied with a tri-packed non-hold open arm.
12) What closer should I use if the opening needs a slide track or double lever arm rather than the parallel arm on the Norton Rixson 7500?
The Norton Rixson 7500 Series uses a top jamb Unitrol parallel arm. For a different arm at the same Grade 1 level, the Corbin Russwin DC5230 Series is a Grade 1 surface closer with a slide track arm standard for pull side mounting, and the DC6200 and DC8200 Series are Grade 1 surface closers with a double lever regular arm for pull side mounting. The Corbin Russwin DC3200 is a Grade 1 regular arm surface mounted closer. All four list a 1-3/4 inch door thickness.
13) Is the Arrow DCN500DP a replacement for the Norton Rixson 7500 door closer?
No. The Norton Rixson 7500 Series is a complete surface mounted door closer. The Arrow DCN500DP is a parallel drop plate for the DCN500 - a mounting bracket, not a closer body, so it will not control a door on its own. Likewise the Stanley Security 327 and 341 are wardrobe pivots, and the Stanley Security 57-0100 is a box of 100 steel machine screws for architectural hinges. If you need a closer, look to a full unit such as the BEST HD8000 Series heavy duty Grade 1 surface mounted closer.
14) What finish does the Norton Rixson 7500 closer come in?
690 dark bronze is the finish offered on this heavy-duty 7500 Series closer. It is a standard architectural bronze that reads dark, so it blends against bronze-anodized aluminum storefront and dark-painted hollow metal frames rather than standing out the way a 689 aluminum finish does. If the rest of the openings in the building are on bronze hardware, this matches without a field paint.
15) Is the closer body covered, or does the mechanism show?
A cover is part of the 7500 Series closer, in plastic or metal, so the hydraulic body is concealed once installed. That is worth knowing against a less-cover unit like the Arrow DCN314 or DCN325, where the cover is ordered separately or omitted deliberately on back-of-house doors to save cost.
16) Is the Norton Rixson 7500 suitable for an exterior door in a coastal or wet environment?
Construction is high-strength, corrosion-resistant metal, which is the reason this closer gets specified on exterior and institutional openings rather than only interior doors. Paired with the 250 lb door capacity and the Unitrol arm that takes the shock of a wind-caught door, it is built for an entrance rather than a corridor.
17) What ADA-rated closers compare to the Norton Rixson 7500?
The Norton Rixson 7500 Series offers adjustable closing speed, backcheck and latching for accessibility compliance. Peers stated as ADA closers include the Calibre CA9901, a Grade 1 tri-pack arm size 2-5 ADA surface mount closer, the Calibre CA4001, a Grade 1 adjustable spring tension ADA hydraulic closer, the Calibre CA8001P, a Grade 1 parallel arm size 1 ADA surface mount closer, the Imperial USA TC4300 Series in heavy duty size 1-6 ADA, and the LCN 1250 Series, a light duty ADA compliant closer in sizes 1-5 with all-weather fluid.
18) The Norton Rixson 7500 comes with a cover - which comparable closers ship without one?
The Norton Rixson 7500 Series carries a plastic/metal cover. Among the peers, the Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover with regular and parallel arm tri-pack, in adjustable spring sizes 1-4 and 1-6 respectively, and the Dexter DCH4000 Series is a Grade 1 tri mount surface closer where the DCH1000 Series is the tri mount version listed with a full cover. Design Hardware 316 Series is a medium to heavy duty closer supplied with a cover and a tri-packed non-hold open arm.
