Norton Rixson PH91NDCP-LH-690 – Frequently Asked Questions

1) Will the Norton Rixson 91DCP concealed closer handle a 4 foot wide by 8 foot tall exterior door?
Yes, that is right at the top of its exterior range. The 91DCP is rated for doors up to 250 lbs, with maximum door sizes of 4' 6" x 8' 0" for interior openings and 4' 0" x 8' 0" for exterior. Exterior gets the tighter width limit because wind load and stack pressure work against the closer. If your exterior leaf is wider than 4 feet, this is not the closer for it.
2) Is the 91DCP offset hung or center hung, and does that change my door prep?
Offset hung. The 91DCP is a single acting offset hung closer, so the door pivots on an offset pivot set inboard from the edge and swings one direction only. That is a different frame and door prep from a center hung closer, which pivots on the door centerline and can be made double acting. If your opening is prepped center hung, look at a center hung unit instead, such as the Dorma RTS88 Series RTS01, which is center hung side load and single or double acting.
3) Which 91DCP do I order for an ADA opening, and what is the difference in spring power?
Order the PH91DCP for ADA. Spring power is the whole difference: the PH91DCP uses size 1-3 settings for the lighter opening force ADA accessible openings need, while the standard 91DCP uses size 3-6 for larger doors and fire rated openings. When ordering you pick this on the rating option, which offers ADA Compliant, ADA and Wood Frame, Standard, or Wood Frame. Do not put a 3-6 spring on an ADA opening and expect to pass the push force test.
4) Can I use the Rixson 91DCP concealed closer in a wood frame, or is it aluminum only?
Wood works. The 91DCP mounts in aluminum, hollow metal, or wood frames, and there are dedicated Wood Frame and ADA and Wood Frame rating options to specify when you order. For aluminum, the frame header has to be at least 1-3/4" x 4" to take the closer body. Measure the header before you commit, since a narrow storefront tube will not accept it.
5) Do I have to specify handing on the Norton Rixson 91DCP?
Yes. It is a handed closer, ordered Left Hand or Right Hand, because it is single acting offset hung and the body is built for one swing direction. Stand outside the door on the side it swings away from: hinges on your left is left hand, hinges on your right is right hand. Get it backwards and the unit will not work in that opening.
6) Is the Rixson 91DCP fire rated and does it meet Grade 1?
Both. The 91DCP carries ANSI/BHMA A156.4 Grade 1 and is UL-cUL fire rated up to 3 hours. For a fire rated opening you want the standard 91DCP with the 3-6 spring range rather than the lighter PH91DCP, since the door has to close and latch positively against the frame.
7) What is the closest equivalent to the Norton Rixson 91DCP overhead concealed closer from another manufacturer?
The Sargent 268 is the nearest match. Like the 91DCP, the Sargent 268 is an overhead concealed door closer built with a cast iron body, rated heavy duty and certified ANSI/BHMA Grade 1. The 91DCP is offset hung, single acting, and carries a Grade 1 rating with heavy duty construction for high traffic openings, so the two land in the same duty class for commercial interior and exterior doors. Confirm the hang type on the opening before swapping: the 91DCP is prepped for offset hung installation.
8) I need a concealed closer for a center hung aluminum storefront door - is the 91DCP the right one?
No. The Norton Rixson 91DCP is an offset hung, single acting closer. For a center hung aluminum door and frame, the Dorma RTS88 series RTS01 is the applicable unit: it is an overhead concealed closer for center hung side load applications, double or single acting, for aluminum door and frame, and it is non-handed. That non-handed construction also means one part number covers both openings, where the 91DCP is ordered left hand or right hand.
9) I need a concealed closer that holds the door open - which one do I order?
The Norton Rixson 91DCP is offered in a hold open arm function as well as non hold open, so the hold open is selected when ordering rather than added later. Among the alternatives, the CRL Jackson 20-101M-09 heavy duty body and the 20-101M-01, 20-101M-03 and 20-101M-17 bodies are all non hold open units, so they will not hold the leaf back at the stop. If the opening needs a door that stays open for carts or deliveries, order the 91DCP with the hold open arm function.
10) Can I get the 91DCP with a hold open arm?
Yes, arm function is an ordering choice of Hold Open or Non-Hold Open, so specify it on the order. The base 91DCP closer body itself carries no hold open feature, so if you want the door to stand open you have to call out the hold open arm rather than adding it later. On a fire rated opening, hold open is generally not permitted unless it releases on alarm, so check the opening's requirements before you spec it.
11) How does the 91DCP hold up in a high traffic entrance, and what makes it heavy duty?
Cast iron body with a 1-1/4" piston diameter, rated heavy duty and high traffic for commercial use. The larger piston bore is what lets it control a 250 lb door repeatedly without fading. Closing speed and latch are set with staked brass adjusting valves, so once a maintenance tech dials it in the settings stay put. For a school or hospital entrance running all day, that is the construction you want rather than a regular duty unit.
12) Can I standardize on one concealed closer across a building with mixed door sizes and ADA entries?
Yes, and the 91DCP Series is built for that. One series covers the range: adjustable spring size lets you set closing force per opening, the standard unit at 3-6 for large or fire rated doors and the PH91DCP at 1-3 for ADA accessible entries, all in the same Grade 1 A156.4 offset hung body and the same finish. Your techs learn one adjustment procedure and you stock one arm and cover type. Handing is still per opening, so keep a count of left hand and right hand leaves before you place the order.
13) What is the difference between the Norton Rixson 91DCP and the Sargent 278?
The arm. The Sargent 278 is an overhead concealed closer with an exposed arm, so the closer body is hidden in the header but the arm remains visible on the door face. The 91DCP is supplied with a dress cover plate and is built for concealed operation where the visual impact at the header is kept minimal. Both are heavy duty Grade 1 units; the 278 is heavy duty and ANSI/BHMA Grade 1 as well. Choose on how much hardware the architect will accept in view at the head of the opening.
14) Is there a lighter duty overhead concealed closer than the 91DCP for a low traffic interior door?
The CRL Jackson 20-101M-01 is a regular duty overhead concealed door closer body, non hold open, with a 105 degree stop, and the 20-101M-03 is the same regular duty body with a 90 degree stop. The Norton Rixson 91DCP is a heavy duty Grade 1 unit rated for high traffic, which is more closer than a low traffic interior opening usually calls for. Note that the CRL Jackson units are body only, so any arm, spindle, or cover the opening needs is ordered separately, while the 91DCP includes a dress cover plate.
15) Which concealed closers besides the 91DCP have adjustable spring power?
The CRL Jackson 20-101M-17 is an adjustable spring power overhead concealed closer body, non hold open, 105 degree. The Norton Rixson 91DCP also uses an adjustable size spring, set 3 to 6 for larger doors and fire rated openings, or 1 to 3 on the PH91DCP for ADA opening force. Adjustable power matters when one part number has to cover several openings of different width, so the field can tune the closing force instead of stocking multiple fixed sizes.
16) Is the Dormakaba ITS9613 an alternative to the Norton Rixson 91DCP?
It is a Grade 1 concealed overhead door closer from the ITS96 series, so it sits in the same certification class as the 91DCP, which is certified to ANSI/BHMA A156.4 Grade 1. The 91DCP is offset hung and single acting, carries a dress cover plate, and is ordered in a handing, so verify the hang type and prep of the opening before substituting either way. Where the spec sheet calls only for a Grade 1 concealed closer, both meet that line.
17) Can I use a CRL Jackson heavy duty concealed closer in place of the Norton Rixson 91DCP on a wood frame opening?
Check what is in the frame first. The CRL Jackson 20-101M-09 is a heavy duty overhead concealed closer body only, non hold open with a 105 degree swing. The Norton Rixson 91DCP is ordered against a rating option that includes a wood frame configuration, and an ADA and wood frame configuration, which is how the wood frame opening gets addressed at the order line rather than in the field. On a wood frame job where ADA opening force is also required, the ADA and wood frame option on the 91DCP covers both in one part number.
18) What finishes does the Norton Rixson 91DCP concealed closer come in to match the rest of my hardware?
Fifteen: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 613E dark oxidized satin bronze, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 689 aluminum, 690 dark bronze, 691 light bronze, 693 flat black, 696 satin brass painted, plus BSP black suede powder and WSP white suede powder. Since the closer body is concealed in the header, the finish you are matching is the exposed dress cover and arm, so pick the BHMA number already on the openings, typically 689 or 690 on aluminum storefront.
