Norton Rixson 9ADJ-526-689 – Frequently Asked Questions

1) How do I pick the right size Norton Rixson 9ADJ Checkmate for my door width?
Size the 9ADJ by door opening width and hanging method. The ranges are 24 to 28 inches butts offset; 28-1/16 to 33 inches butts offset or 30 to 36 inches center hung; 33-1/16 to 38 inches butts offset or 36-1/16 to 41 inches center hung; 38-1/16 to 43 inches butts offset or 41-1/16 to 46 inches center hung; and 43-1/16 to 48 inches butts offset or 46-1/16 to 50 inches center hung. Measure the door leaf width, then read the column that matches how the door is hung.
2) Can the Norton Rixson 9ADJ be used on a double acting door?
No. The 9ADJ Checkmate is a single acting device, for doors that swing one way only, interior or exterior. A double acting door that swings both directions needs a different control.
3) Do I have to order the Norton Rixson 9ADJ as a hold open, or can I get stop only?
Both are ordered separately. The 9ADJ comes in a Hold Open function and a Stop function, so decide up front whether the door should stay parked open or just be stopped at the limit. Pick Stop where a fire or smoke door must be free to close, and Hold Open where staff want the door to stay put.
4) How far will the 9ADJ Checkmate let the door open, and can that angle be changed later?
Maximum opening is 110 degrees, and 105 degrees on center hung 30 to 36 inch doors. The degree of opening is fully adjustable in the field on the slide track arm, so if a room gets rearranged you can reset the stop point without replacing the unit.
5) Is the Norton Rixson 9ADJ Checkmate Grade 1 and UL listed?
Certain models of the 9ADJ carry ANSI/BHMA A156.8 Grade 1 certification, and the stop functions are UL listed. That is the pairing an institutional spec usually asks for on a heavy duty overhead stop.
6) Is there a lighter duty overhead stop and holder to use on an interior office door instead of the 9ADJ Checkmate?
Yes. The Glynn-Johnson 450 Series is a light to medium duty surface overhead door holder and stop, and the Sargent 1540 is a medium duty surface mount stop and holder with a 110 degree opening, the same opening angle the 9ADJ Checkmate reaches. The Norton Rixson 9ADJ is a heavy duty unit intended for high traffic, high abuse commercial and institutional openings. On a low traffic interior office or a private door where abuse is not the concern, the 450 Series or the Sargent 1540 covers the same stop and hold function in a lighter duty build.
7) What is the closest heavy duty equivalent to the Norton Rixson 9ADJ Checkmate overhead stop from another manufacturer?
The Sargent 590 is the nearest heavy duty match. Both are surface mount overhead door stops and holders built for heavy duty commercial service, and both carry a Grade 1 rating. The Sargent 590 uses bronze construction, while the 9ADJ Checkmate is built around a 1-3/16 inch square channel with a slide track arm, a slider cam and shock block, and a heavy shock absorber spring giving 5 to 7 degrees of compression before dead stop. The Glynn-Johnson 90 Series is the other heavy duty surface overhead holder and stop in the same class. If a facility is standardizing on one heavy duty surface stop across openings, all three sit in the same duty tier.
8) What overhead stop should be used when the door or frame cannot take a surface mounted unit like the 9ADJ Checkmate?
The Norton Rixson 9ADJ Checkmate is a surface mounted overhead stop and holder, so it needs exposed mounting area on the door face and the frame soffit. Where the specification calls for the stop to be hidden, the ABH 4000 Series is a concealed mount overhead stop and holder in a medium duty build, and the ABH 4000RA Series is a concealed mount medium duty overhead door holder and stop with adjustable opening control. Concealed units require the door and frame to be prepped for the template, so confirm the prep before ordering against a surface application.
9) Can a DORMA 701F friction stop be used in place of the Norton Rixson 9ADJ Checkmate?
They are not the same device. The DORMA 701F is a standard duty surface applied friction stop covering a 21 inch to 27 inch door opening, so it holds by friction and is sized for narrow openings. The 9ADJ Checkmate is a heavy duty unit with a positive hold open function and a stop function, a heavy shock absorber spring, and door opening models spanning 24 inch to 28 inch butts offset up through 43-1/16 inch to 48 inch butts offset, plus center hung ranges. On a wide opening, or where a positive hold open is required rather than friction hold, the 701F will not stand in for the 9ADJ.
10) For a door opening wider than 36 inches, which overhead stops cover the range and which do not?
The Norton Rixson 9ADJ Checkmate is ordered by door opening range, and the ranges run through 43-1/16 inch to 48 inch butts offset and 46-1/16 inch to 50 inch center hung, so wide openings are covered by model selection. Among the peers, the ABH 3400 Series is a surface mount overhead stop and holder for 24 inch to 36 inch door frames and the DORMA 701F friction stop covers a 21 inch to 27 inch door opening, so neither reaches a 48 inch opening. Match the door width to the range before substituting.
11) Which overhead stop meets a Grade 1 specification on an institutional door?
The Norton Rixson 9ADJ Checkmate is certified to ANSI/BHMA A156.8 Grade 1 on certain models, with UL listed stop functions. Among the peers, the Sargent 590 heavy duty surface mount stop and holder is Grade 1, and the Sargent 1540 surface mount stop and holder is also Grade 1 in a medium duty build. Where the drawing calls for Grade 1 plus heavy duty service, the 9ADJ and the Sargent 590 both answer it; where Grade 1 alone is the requirement, the 1540 also meets it.
12) What comes in the box with the Norton Rixson 9ADJ, and what else do I need to buy?
The screw packet is complete: thru-bolts for the door plus wood and machine screws for the frame. Torx screws for the exposed fasteners are a separate option you select when ordering, worth taking on detention, dorm, or other high abuse openings where someone will go after the heads. Surface mount means no pocket routed into the door or frame, just template, drill, and bolt through.
13) Will the 9ADJ stop bang the door hard at the end of its travel?
No. A heavy shock absorber spring gives 5 to 7 degrees of compression before the dead stop, so the door decelerates instead of slamming into a hard limit. That cushion is what keeps hinges, frames, and closer arms from taking the shock in a high traffic corridor.
14) What finishes does the Norton Rixson 9ADJ Checkmate come in so I can match the rest of my door hardware?
Seventeen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613E dark oxidized satin bronze, 618 bright nickel, 619 satin nickel, 622 black painted, 629 bright stainless, 630 satin stainless, 652 satin chromium, 689 aluminum, 690 dark bronze, 691 light bronze, 696 satin brass painted, BSP black suede powder, and WSP white suede powder. 630 and 689 are the usual matches for commercial closers and exit devices already on a building.
15) What is the difference between the Norton Rixson 9ADJ and a concealed overhead stop?
The 9ADJ mounts on the surface of the door and frame, so it installs on an existing opening without morticing a channel into the door top or the frame soffit. A concealed unit like the ABH 4000 Series hides in that pocket for appearance, but it needs the prep and it is a medium duty design. On a high abuse opening where looks are secondary, the surface unit is the easier retrofit and the heavier build.
16) What is a comparable heavy duty surface overhead stop and holder to the Norton Rixson 9ADJ?
Two direct peers in the same class: the Glynn-Johnson 90 Series heavy duty surface overhead holder and stop, and the Sargent 590 Series heavy duty surface mount stop/holder, which is Grade 1. All three are surface applied heavy duty units combining stop and hold open, so the deciding factors are your door opening width, the finish you need to match, and which brand the rest of the building is standardized on.
17) Which other overhead stops have an adjustable degree of opening like the Norton Rixson 9ADJ?
The 9ADJ Checkmate has a fully adjustable degree of opening up to 110 degrees, set at the slide track arm, which lets the stop point be changed later if the opening changes. Among surface mount peers, the ABH 3300A Series is a surface mount overhead stop and holder with adjustable opening control. On the concealed side, the ABH 4000RA Series carries adjustable opening control in a medium duty concealed build. Fixed-degree stops in the same family, such as the ABH 3400 Series for 24 inch to 36 inch door frames, are set by the model ordered rather than adjusted in the field.
18) If only a stop is needed and not a hold open, is there a simpler option than the 9ADJ Checkmate?
The 9ADJ Checkmate itself is ordered in either a Stop function or a Hold Open function, so the stop-only version is available without changing manufacturers. If a lighter build suits the opening, the Glynn-Johnson 450 Series is a light to medium duty surface overhead door holder and stop, and the DORMA 701F is a standard duty surface applied friction stop for a 21 inch to 27 inch door opening. The heavy duty 9ADJ still applies where the door takes abuse even in stop-only service.
19) Will an overhead stop work on a double acting door if the 9ADJ Checkmate does not?
The Norton Rixson 9ADJ Checkmate is a single acting door control, for interior or exterior single acting doors at 1-3/4 inch minimum door thickness, so it is not the part for a door that swings both ways. Confirm the swing before comparing it against surface mount peers such as the ABH 3300A Series or the Glynn-Johnson 90 Series, since an overhead stop is selected against the swing and the door opening width first and the finish second.
