Norton Rixson 1ADJ-336-BSP – Frequently Asked Questions

1) How far does the 1ADJ Checkmate let the door swing open?
110 degrees maximum on most applications, and 105 degrees on center hung doors in the 30 to 36 inch range. The degree setting is adjustable in the field, so you can dial the stop back to whatever the wall, casework, or adjacent door actually allows. It is not a fixed-angle stop.
2) How do I pick the right 1ADJ size for my door width?
Size is by door opening width, and butt hung and center hung doors read on different scales. The five 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 leaf width and note which way the door is hung before you order, because a 36 inch door lands in a different bracket depending on whether it is on butts or center hung.
3) Do I need the hold open version of the 1ADJ, or just the stop?
Both functions are offered on the Checkmate 1ADJ, and you pick one when you order. The stop only version arrests the door at your set degree and lets it close again. The hold open version catches and parks the door at the open position until someone pulls it free, which is what you want at a receiving door, a corridor door being propped for moves, or a classroom door held back during passing periods. If the door is on a fire rated opening it should not be held open by a mechanical holder, so specify stop only there.
4) Will a concealed overhead stop hold up on an abusive door like a stairwell or a loading corridor?
That is what the 1ADJ is built for. It is a heavy duty, commercial rated unit with a slider cam and shock block, plus a heavy shock absorber spring that gives 5 to 7 degrees of compression before it reaches dead stop. That compression is the point: the door decelerates instead of slamming into a hard stop, which is what kills lighter overhead stops on high traffic openings. If the traffic is lighter, a medium duty concealed unit like the Glynn-Johnson 410 Series or the Sargent 1530 covers it.
5) Concealed overhead stop or surface mounted, which should I use?
Concealed, like the 1ADJ Checkmate, means the arm and track are hidden in a routed pocket in the top of the door with the shoe in the frame soffit. Nothing shows when the door is closed, and there is nothing to grab or vandalize. The tradeoff is that the door has to be machined for it, which is straightforward on new doors and on hollow metal, but is real work on an existing installed door. Surface mounted units like the Glynn-Johnson 70 Series or the extra heavy duty 79 Series screw to the face of the door and the frame, so they retrofit onto an existing opening with no routing. If the doors are already hung and you are adding stops after the fact, surface is usually the practical answer.
6) What is the closest heavy duty concealed overhead stop and holder to the Norton Rixson 1ADJ Checkmate?
The Glynn-Johnson 100 Series is the nearest peer: heavy duty concealed overhead door holders and stops, the same class of device as the 1ADJ Checkmate, which is a heavy duty concealed-mount overhead stop and holder with a slide track arm. The Sargent 690 is the other close match, a heavy duty overhead concealed stop/holder carrying ANSI Grade 1 compliance, matching the Grade 1 rating the 1ADJ carries on certain models. All three mount concealed in the door and frame rather than on the face, so the door prep concept is the same; confirm the specific door width band before ordering, since the 1ADJ is sold in opening ranges from 24 inch to 48 inch butts offset.
7) Which concealed overhead stops carry an ANSI Grade 1 rating for a spec that calls for it?
The Sargent 690 is a heavy duty overhead concealed stop/holder with ANSI Grade 1 compliance, and the Sargent 1530 concealed mount stop/holder is also listed Grade 1. The Norton Rixson 1ADJ Checkmate is Grade 1, certified to ANSI/BHMA A156.8 on certain models. Where a facility standard calls out A156.8 Grade 1 on concealed overhead stops, verify the specific model number in the series against the certification, since the 1ADJ certification applies at the model level.
8) Can the 1ADJ be used on a double acting door that swings both ways?
Yes, the Checkmate 1ADJ is rated for single or double acting door swing, so it suits balanced and center hung doors that push both directions as well as ordinary butt hung leaves. On center hung doors, note the opening range shifts and the maximum angle drops to 105 degrees on 30 to 36 inch leaves.
9) Is the Norton Rixson Checkmate 1ADJ ANSI Grade 1?
Grade 1 is the stated grade, with certain models certified to ANSI/BHMA A156.8, Grade 1. For a spec-driven job where the submittal has to show the certification, confirm the specific size and function you are ordering falls in the certified group. Grade 1 is the top tier under A156.8 for overhead holders and stops.
10) What do I have to specify when ordering a 1ADJ Checkmate?
Four things. The door opening range that matches your leaf width and hanging method, the function (hold open or stop), the finish, and whether you want Torx security screws on the exposed fasteners. The Torx option is a yes or no choice made at order time, so decide it before the order goes in rather than after the units land on site.
11) Is there a tamper resistant fastener option for a detention or behavioral health door?
Torx security screws are available for the exposed fasteners on the Checkmate 1ADJ, ordered as a yes or no option. That covers the usual concern on high security areas, holding cells, and psychiatric units where a standard Phillips head on an accessible overhead stop is a liability. The rest of the mechanism is concealed inside the door and frame, so the Torx heads are the only exposed hardware to secure.
12) I only need a stop, not a holder, and the budget is tight. Is the 1ADJ overkill?
For a light traffic interior door, probably. The Checkmate 1ADJ is a heavy duty commercial unit with an adjustable arm and a shock absorbing mechanism, and it is priced and specified for high abuse openings. If you just need a door not to hit a wall on a normal office or apartment interior opening, a standard duty concealed unit does the job: the Don-Jo 3023 for a 30 inch door or the 3024 for a 36 inch door are concealed overhead stops in satin stainless, and the DORMA 711F is a standard duty concealed friction stop for 21 to 27 inch openings. Where the door gets kicked open all day, stay with the heavy duty unit.
13) Can I adjust the stop angle on the Checkmate 1ADJ after it is installed?
Yes. The adjustable slide track arm rides in a 1-3/16 inch square channel and can be reset in the field, so if the room changes, furniture moves, or the original angle turns out to be wrong on site, you reset the stop point without pulling the unit or ordering a different part. That is the difference between the 1ADJ and a fixed-degree concealed stop.
14) What is the difference between the Norton Rixson 1ADJ and the ABH 1000 Series concealed overhead stop?
The ABH 1000 Series is a heavy-duty concealed mount overhead door stop with a fire rating - a stop-only device. The Norton Rixson 1ADJ Checkmate is ordered as either a Stop or a Hold Open function and carries a hold open feature, so if the opening needs the door to stand open, the 1ADJ hold open version or one of the ABH holder models applies rather than the plain 1000. ABH's stop and holder versions are the 1000A, 1000RA and 1000SA Series, all heavy-duty concealed mount with adjustable opening control, which parallels the field-adjustable degree settings on the 1ADJ adjustable slide track arm.
15) Is a DORMA 711F friction stop a substitute for a Norton Rixson 1ADJ Checkmate?
No, in two respects. The DORMA 711F is a standard duty concealed friction stop covering a 21 inch to 27 inch door opening, while the 1ADJ Checkmate is a heavy duty unit whose smallest band starts at 24 inch to 28 inch butts offset and runs up to 43 1/16 inch to 48 inch butts offset. It is also a friction stop rather than a stop and holder, where the 1ADJ is ordered as Stop or Hold Open. For a heavy duty DORMA option, the 900 Series covers heavy duty stops and holders.
16) We standardize on one concealed overhead stop across a building with doors from 24 to 48 inches wide. Which line covers that range?
The Norton Rixson 1ADJ Checkmate is sold in five opening bands from 24 inch to 28 inch butts offset up to 43 1/16 inch to 48 inch butts offset, with center hung ranges called out alongside, so one series covers the full width spread with a different band per door size. Among the peers, the Don-Jo 3023 and 3024 are sized to specific doors - 30 inch and 36 inch respectively - so a mixed-width building would take more than one part number from that line. The Glynn-Johnson 100 Series and the Sargent 690 are the other heavy duty concealed lines to evaluate for a facility standard.
17) Which overhead stop should I use on a door that swings both ways?
The Norton Rixson 1ADJ Checkmate is rated for single or double acting door swing, so it applies to a double acting opening directly, in the 110 degree maximum opening range - 105 degrees for center hung 30 to 36 inch doors. Among the concealed peers, the Glynn-Johnson 100 Series is described as non-handed multi-function, which likewise avoids a handed part number. Confirm the center hung opening band when ordering the 1ADJ, since the door opening options list center hung ranges separately from butts offset.
18) Can I match the 1ADJ overhead stop to the finish on the rest of my door hardware?
Seventeen finishes are offered on the Checkmate 1ADJ, covering the common BHMA numbers a building is already standardized on: 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, plus BSP black suede powder and WSP white suede powder. For a property manager matching existing openings, 630 satin stainless and 689 aluminum are the two that turn up most on commercial doors.
19) Can I standardize the same overhead stop across a whole building with different door widths?
Yes, and that is the usual way the Checkmate 1ADJ gets specified. One series, one finish, one function covers openings from 24 inches through 48 inches butts offset (up to 50 inches center hung) by changing only the size bracket. Maintenance stocks one style of spare, the doors all behave the same at the stop, and the finish matches across the whole floor. Order per opening width, but keep the finish and function constant.
