Norton Rixson 7570-689 – Frequently Asked Questions

1) Will a Norton Rixson 7570 closer handle a heavy exterior door in a correctional or psych unit?
The 7570 Series is built for exactly that. It's a heavy duty, Grade 1 surface closer rated for doors up to 250 lbs, with adjustable spring sizes 1 through 6 so you can dial the power to the door width and any stack pressure you're fighting. Non-handed, and it mounts on interior or exterior openings. The cast aluminum body, orbital riveted elbow and arm joints, and Torx drive screws with security pins are the reason it shows up in correctional and mental health work: there's nothing an occupant can unscrew.
2) Is the Norton Rixson 7570 fire rated, and does it meet ADA closing force rules?
Yes on both. The 7570 carries UL 10C positive pressure fire rating up to 3 hours, so it's usable on rated openings, and it meets ADA requirements along with ANSI/BHMA A117.1 accessibility. It is certified to ANSI/BHMA A156.4 Grade 1. One caution for ADA work: on a fire rated door you cannot use the hold open arm, and you have to set the spring size low enough to meet the opening force limit for your occupancy while still closing and latching the door.
3) Which arm should I order on the 7570 - parallel rigid, regular rigid, slide track, or CloserPlus?
Nine arm choices are offered and they solve different openings. Regular Rigid mounts on the pull side and gives the most efficient power, but the arm projects into the opening. Parallel Rigid puts the closer on the push side face of the door with the arm tucked under the frame soffit, which is the usual pick for abuse-prone and institutional openings. Pull Side and Push Side Slide Track give a low-profile track instead of a projecting arm, which is the cleanest look and the hardest to grab. CloserPlus and CloserPlus Spring are the Unitrol-style arms that stop the door before it hits an adjacent wall or overhead obstruction, with the spring version absorbing wind and abuse loads; Unitrol Parallel is also offered. Hold open is available on the CloserPlus arms; the rigid, slide track and Unitrol Parallel options listed are non-hold open.
4) How is the 7570 different from a standard heavy duty closer like the BEST EHD9000 or Falcon SC71A?
All three are heavy duty surface closers, and the BEST EHD9000 is Grade 1 with adjustable spring sizes 1-6 just like the 7570, as is the Falcon SC71A heavy duty series. The difference is the security package. The 7570 adds permanently riveted arm joints, Torx security-pin fasteners and a security cover so the unit can't be disassembled or readjusted by an occupant. If the opening is a normal commercial corridor or entrance, a conventional heavy duty Grade 1 closer does the job. If it's a cell, a dayroom, a dormitory, or a behavioral health unit, the tamper resistance is the whole reason to pay for the 7570.
5) What is the closest heavy-duty Grade 1 alternative to the Norton Rixson 7570 Series security closer?
The Norton Rixson 7570 Series is a heavy duty, ANSI/BHMA A156.4 Grade 1 surface closer with adjustable spring sizes 1-6 and a cast aluminum body. The closest peers on duty and grade are the BEST EHD9000 Series, an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1-6, and the Falcon SC71A Series, a heavy-duty Grade 1 surface-mount closer. The Sargent 1431 Powerglide is also heavy duty Grade 1 with adjustable spring power. The difference is the 7570 security construction - orbital riveted joints, Torx drive screws with security pins, and a security cover - which the peers are not described as carrying.
6) We do not need tamper resistance - what is a simpler Grade 1 closer for a standard office door?
For an opening with no security exposure, medium and light duty Grade 1 closers cover it without the 7570 Series security hardware. The BEST HD7000 Series is a medium duty Grade 1 surface closer with adjustable spring power and backcheck control, the Sargent 1331 is a medium duty Grade 1 closer with a universal aluminum body, and the Falcon SC81A Series is a medium duty Grade 1 cast aluminum closer. For lighter interior doors, the BEST SL6000 Series is Grade 1 light duty. The 7570 Series remains the choice where the closer itself must resist disassembly.
7) Which closers besides the Norton Rixson 7570 offer a slide track pull side mount?
The Norton Rixson 7570 Series is available with pull side and push side slide track arms as well as regular rigid, parallel rigid, CloserPlus and Unitrol parallel arms. If a slide track arrangement is what the opening needs, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm for pull side mounting, 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.
8) Can I get the Norton Rixson 7570 with delayed action for a wheelchair-accessible door?
Delayed action is a selectable option on the 7570, ordered as a yes or no at the time of purchase, and the series does include a delay function. It holds the door near full open for a few seconds before the sweep begins, which is what you want on accessible entries, patient room doors, and any opening where someone needs extra time to clear the threshold. If you don't specify it you get the standard sweep and latch cycle only, so call it out on the order.
9) What is enhanced backcheck on the 7570 and do I need it?
Enhanced backcheck is a required yes or no selection when you order the 7570. Backcheck cushions the door near the end of the opening swing so it isn't slammed into the adjacent wall or the stop. Specify it on exterior doors that catch wind, on stairwell and vestibule doors, and anywhere occupants throw the door open. On a protected interior opening with a wall stop already in place, the standard configuration is usually enough.
10) Does the Norton Rixson 7570 come with a security cover, and what keeps it from being tampered with?
A security cover is standard on the 7570. Beyond the cover, the anti-tamper work is in the construction: the elbow and the arm shoe/soffit plate joints are permanently orbital riveted so they cannot be taken apart, machine screws are Torx drive with security pins, and the valves are staked so they can't drift or be casually readjusted. That combination is what separates it from a standard commercial closer wearing a metal cover.
11) I need a closer for a light interior office door, not a secure facility. Is the 7570 overkill?
For a light interior door it is more closer than the opening needs, and the security hardware adds cost you won't use. Look at a light duty Grade 1 unit instead: the BEST SL6000 Series is a light duty Grade 1 surface closer with adjustable spring sizes, the Arrow DCN314 covers regular or parallel arm in a tri-pack with sizes 1-4, and the LCN 1250 Series is light duty with sizes 1-5. Save the 7570 for the 250 lb doors and the openings where tampering is the real risk.
12) Do I have to specify handing when I order a Norton Rixson 7570?
No. The 7570 is a non-handed closer, so one unit works on a left or right hand door. What you do have to get right is the mount and arm: pull side, push side parallel, or slide track, since the arm and any drop plate or bracket follow the mounting side, not the handing.
13) Can I use the 7570 on a door that opens into a wall or under a low overhead?
That's what the CloserPlus arms are for. The CloserPlus and CloserPlus Spring arms are offered on the 7570 in both hold open and non-hold open, and they stop the door at a set opening point so it never reaches the wall or obstruction. The spring version also absorbs the shock of someone forcing the door past the stop, which matters on wind-loaded exterior openings and in abusive environments. Unitrol Parallel is offered as a non-hold-open alternative.
14) Is hold open available on the Norton Rixson 7570?
Hold open is available, but only on the CloserPlus and CloserPlus Spring arms. The Regular Rigid, Parallel Rigid, slide track and Unitrol Parallel arm options are non-hold open. Keep in mind hold open is not permitted on a fire rated opening unless it's released by the fire alarm, so on rated doors order a non-hold-open arm.
15) Is a tri-pack closer a substitute for the Norton Rixson 7570 Series?
Tri-pack closers such as the Arrow DCN325, the Accentra 2701 Series and the Design Hardware 416 Series ship with regular and parallel arm mounting options in one carton, which the 7570 Series does not - the 7570 is ordered with the specific arm you need, including regular rigid, parallel rigid, CloserPlus and slide track. Tri-packs also do not carry the 7570 orbital riveted joints, Torx security screws and security cover. Where the requirement is field flexibility on mounting, a tri-pack answers it; where the requirement is a closer that resists disassembly, it does not.
16) I need hold open and delayed action - which closers besides the Norton Rixson 7570 offer both?
The Norton Rixson 7570 Series is ordered with or without delayed action and with hold open or non-hold open CloserPlus and CloserPlus Spring arms. Among comparable closers, the Orca Hardware BHDC1958 Series is offered as a hold open model with parallel bracket and separately as a delayed action model, and the Accentra 51 Series is a hold open tri-packed closer in sizes 1-6. Those are two separate order choices on the Orca rather than one closer covering both.
17) For a 250 lb institutional door, what else carries spring sizes up to 6 like the Norton Rixson 7570?
The Norton Rixson 7570 Series handles doors up to 250 pounds with adjustable spring sizes 1-6. Other size 1-6 adjustable closers include the BEST EHD9000 Series extra heavy-duty Grade 1, the Dorma 8916-JT Grade 1 heavy duty jamb track closer, the Imperial USA TC4300 Series Grade 1 heavy duty ADA closer, and the LCN 1450, a medium duty cast aluminum closer with spring sizes 1-6. Spring range alone does not equal duty level, so match the duty rating to the traffic as well.
18) What is the difference between the Norton Rixson 7570 and the BEST HD8000 Series?
Both are heavy duty Grade 1 surface mounted closers. The BEST HD8000 Series is a general-purpose heavy duty Grade 1 closer, while the Norton Rixson 7570 Series is built for abuse-prone openings with permanent orbital riveted elbow and arm joints, Torx drive machine screws with security pins, and a security cover. The 7570 is also offered in nine finishes including 613E dark oxidized satin bronze, 689 aluminum, 693 flat black and white suede powder.
19) What finishes does the Norton Rixson 7570 come in for matching existing door hardware?
Nine finishes are offered: 689 Aluminum, 690 Dark Bronze, 691 Light Bronze, 693 Flat Black, 694 Medium Bronze, 696 Satin Brass Painted, 613E Dark Oxidized Satin Bronze, plus BSP Black Suede Powder and WSP White Suede Powder. For a building already standardized on aluminum storefront, 689 is the usual match; 690 pairs with dark bronze storefront. The two suede powder finishes are the textured options if you want something that hides handling marks in high-traffic corridors.
