Norton Rixson UNIJ7500-689-3-1/4-REVEAL – Frequently Asked Questions

1) Will the Norton Rixson 7500 Series door closer handle a heavy exterior door?
The 7500 Series surface closer is rated for doors up to 250 lbs and carries a Heavy Duty rating with a high traffic rating, so it suits heavy exterior and main entrance openings in commercial buildings. If your door is heavier than 250 lbs, you need a different closer.
2) What does the top jamb Unitrol parallel arm on the 7500 closer actually do for me?
The Unitrol arm mounts at the top jamb in a parallel arm configuration, so the closer body sits on the frame face rather than the door, and the arm controls door movement through the swing. It is the setup used where you want stop-side mounting on the frame and controlled operation on a heavy exterior door. If your opening needs the closer on the pull side of the door itself, this configuration is not the one to order.
3) Is this closer ANSI Grade 1 for a school or hospital spec?
It is certified to ANSI/BHMA A156.4 Grade 1 and is a commercial rated product, which is the grade normally written into institutional door hardware specs. Combined with the high traffic rating, it fits educational, healthcare and government openings.
4) I need a hold open closer instead of the Norton Rixson 7500 Series. What should I order?
The Norton Rixson 7500 Series does not have a hold open feature. If the opening needs to stay open, the Accentra 51 Series uses a tri-packed hold open arm with spring sizes 1 to 6, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket. The Stanley Security A45-501HL uses a long hold open arm in a top jamb mounting, which is the closest hold open match to a top jamb application.
5) What is the closest Grade 1 heavy duty surface closer to the Norton Rixson 7500 Series if I need a different brand?
The Norton Rixson 7500 Series is an ANSI/BHMA A156.4 Grade 1 heavy duty surface mounted closer. Comparable Grade 1 heavy duty surface closers include the BEST HD8000 Series, the Falcon SC71A Series, the Sargent 1431 Powerglide, and the LCN 1460T. All four are catalogued at Grade 1 with a heavy duty rating, so any of them can be specified where a heavy duty surface closer is called out.
6) Which closers besides the Norton Rixson 7500 Series can be top jamb mounted?
The Norton Rixson 7500 Series uses a top jamb Unitrol parallel arm. Other closers offering a top jamb mounting include the Dexter DCH1000, DCH4000, DCL2000 and DCM1000 Series, all of which are tri mount Grade 1 closers that can be regular, parallel or top jamb mounted. The Stanley Security A45-501HL is also a top jamb mounting. The Dorma 8916-JT is a Grade 1 heavy duty jamb track closer with frame face mounting on the pull side, adjustable size 1 to 6.
7) I need an ADA barrier free closer rather than the Norton Rixson 7500 Series. What are the options?
Options catalogued as barrier free or ADA include the Cal-Royal 500S Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF from the 900 Series, the Calibre CA4001 adjustable spring tension ADA hydraulic closer, the Calibre CA8001P parallel arm size 1 ADA closer, and the Imperial USA TC4300 Grade 1 heavy duty size 1 to 6 ADA closer. The TC4300 is the closest on duty level to the heavy duty Norton Rixson 7500 Series.
8) Can I adjust the closing force after it is installed, or do I order a fixed size?
Spring power is adjustable rather than fixed, so one unit covers a range of door sizes and you tune it on the job. Closing speed, backcheck and latch speed are adjustable as well, which is what you use to dial in an exterior door against wind.
9) Do I have to prep or mortise the door to install this closer?
No mortising. It is a surface mounted closer, so it fastens to the frame and door face using the manufacturer template, which is why it works for retrofits on existing openings as well as new construction.
10) What are the alternatives to the Norton Rixson 7500 if I need a different mounting or duty level?
For heavy duty Grade 1 surface closers in the same class, the BEST EHD9000 Series and BEST HD8000 Series, the Falcon SC71A, and the Sargent 1431 Powerglide are comparable heavy duty options. If you want one unit that can be mounted regular, parallel or top jamb from the same box, the Dexter DCH1000 or DCH4000 tri mount Grade 1 closers cover all three. For a lighter interior door, the BEST HD7000 is medium duty and the BEST SL6000 is light duty.
11) I am standardizing closers across a portfolio of buildings. Is the 7500 a good fleet choice?
For heavy exterior and high traffic openings, yes. One adjustable spring model covers a range of door sizes, it is Grade 1 to A156.4, and the 689 aluminum finish is the common commercial default, so replacement units match what is already hanging. For lighter interior doors in the same portfolio you would pair it with a medium or light duty closer rather than putting this on every opening.
12) The Norton Rixson 7500 Series is more closer than my interior office door needs. What is a lighter option?
For lower traffic interior openings, lighter duty Grade 1 surface closers include the BEST SL6000 Series, the Arrow DC314 from the DC300 Series, and the LCN 1250 Series in sizes 1 to 5 with all-weather fluid. The Falcon SC61A is a light to medium duty cast aluminum closer at Grade 1. The 7500 Series by contrast is a heavy duty closer rated for high traffic and doors up to 250 lbs.
13) I need one closer that can be field mounted regular, parallel or top jamb rather than the fixed arm setup on the Norton Rixson 7500 Series. What works?
The Norton Rixson 7500 Series ships in a top jamb Unitrol parallel arm configuration. If the installer wants one box that covers multiple mountings, tri-pack closers include the Arrow DCN314 with regular and parallel arm and adjustable spring size 1 to 4, the Arrow DCN325 with the same arm set in sizes 1 to 6, the Accentra 2701 Series with tri-pack mounting and sizes 1 to 6, and the Calibre CA9901 Grade 1 tri-pack arm closer in sizes 2 to 5.
14) Is the Cal-Royal 400 Series an equivalent to the Norton Rixson 7500 Series?
No. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, while the Norton Rixson 7500 Series is certified to ANSI/BHMA A156.4 Grade 1. If the specification calls for Grade 1, stay with a Grade 1 unit such as the Cal-Royal 500S barrier free closer or the Cal-Royal 700S dual valve sized closer with adjustable tube arm.
15) What is the difference between the Norton Rixson 7500 Series and a medium duty closer like the Sargent 1131 or BEST HD7000?
All three are Grade 1. The Sargent 1131 and the BEST HD7000 Series are rated medium duty, while the Norton Rixson 7500 Series is rated heavy duty for high traffic and doors up to 250 lbs. On heavy or abused entrances the heavy duty unit is the match; the medium duty units are aimed at medium traffic commercial openings.
16) Is there a step up from the Norton Rixson 7500 Series for an extra heavy duty entrance?
The BEST EHD9000 Series is an extra heavy-duty Grade 1 surface mounted closer with adjustable spring sizes 1 to 6. The Sargent 281 Powerglide is a Grade 1 heavy duty closer with cast iron construction, which is a heavier body than a cast aluminum unit. The Norton Rixson 7500 Series itself is Grade 1 heavy duty with an adjustable size spring and handles doors up to 250 lbs.
17) My spec calls for delayed action instead of the Norton Rixson 7500 Series. What closer has that?
The Norton Rixson 7500 Series is a standard closing surface closer with adjustable closing speed, backcheck and latching. For delayed action, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket, both for 1-3/4 inch doors.
18) Which Corbin Russwin closer lines compare with the Norton Rixson 7500 Series?
Corbin Russwin offers several Grade 1 surface closers for 1-3/4 inch doors: the DC3200 with a regular arm, the DC6200 and DC8200 with a double lever regular arm in pull side mounting, and the DC5230 with a slide track arm standard in pull side mounting. All are Grade 1 like the Norton Rixson 7500 Series, but the 7500 is configured with a top jamb Unitrol parallel arm rather than a pull side regular arm.
19) What finish does the Norton Rixson 7500 closer come in?
It is supplied in 689 aluminum, the standard painted aluminum finish that matches most commercial closers and aluminum storefront hardware already on the building. The cover is a plastic or metal type.
20) The Norton Rixson 7500 Series has a cover. Which comparable closers come without one?
The Norton Rixson 7500 Series uses a plastic or metal cover. If the job calls for a less cover unit, the Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover with regular and parallel arm tri-pack. If you want a full cover instead, the Dexter DCH1000 Series is a Grade 1 tri mount closer with a full cover.
21) Does a Stanley wardrobe pivot work as a substitute for the Norton Rixson 7500 Series?
No. The Stanley 327 and Stanley 341 are wardrobe pivots, hanging hardware for doors rather than closing devices. The Norton Rixson 7500 Series is a surface mounted hydraulic door closer with adjustable closing speed, backcheck and latching. A pivot does not control the door's closing cycle and cannot replace a closer.
