Sargent 281-O-EN-TB – Frequently Asked Questions

1) Does the Sargent 281 closer need to be ordered by hand, left or right?
No handing to specify. The 281 closer body is non-handed, so the same unit works on a left or right hand door. What you do decide is the mounting: it supports standard (regular arm) mounting on the pull side, top jamb, parallel arm, and track applications.
2) What door weight or width will a Sargent 281 closer handle?
Spring power is field adjustable across sizes 1 through 6, which covers everything from a light interior door up to a heavy exterior opening. It ships set at size 3, so on anything heavier or on a wide exterior door you will be turning the power up during install. On a low-force interior door you adjust down.
3) Can I use the Sargent 281 on a labeled fire door?
Yes. The 281 Series closer is UL listed for fire door applications and ANSI/BHMA Grade 1 certified, so it meets the closing-device requirement on a labeled opening. Note it is a plain closer, not a hold-open unit, so nothing extra is needed to keep it from holding a fire door open.
4) What does thru-bolt mounting mean on this Sargent closer, and when do I need it?
Thru-bolt (TB) means the closer is fastened with bolts that pass all the way through the door and are secured on the opposite face, instead of into tapped or self-drilled holes. It is what you want on hollow metal doors with thin face sheets, on mineral-core or composite doors that will not hold a screw, and on high-abuse openings where a closer has already torn out once. It requires drilling the door through both faces, so check that the door core and any glazing or lite kit allow it before you prep.
5) Does the Sargent 281-O-EN-TB come as a complete closer or just the arm?
Complete closer. You get the 281 closer body with a regular (standard) arm and thru-bolt mounting hardware, in sprayed aluminum enamel finish. The regular arm mounts on the pull side of the door; if you need the closer on the push side you are into a parallel arm or top jamb configuration instead.
6) I need hold-open at the door, not a closer that closes every time. What should I use instead of the Sargent 281-O-EN-TB?
The Sargent 281-O-EN-TB is a surface closer supplied with a regular (standard) arm, which returns the door to the closed position with no hold-open detent. For openings where the door needs to stand open, the LCN 4010-3049 is a hold-open arm with an adjustable elbow function, and the LCN 1250-3049/PA is a hold-open arm assembly with a parallel arm shoe and non-handed, adjustable hold open. Confirm any hold-open arrangement against fire door requirements for the opening, since the 281 closer body is UL listed for fire door applications.
7) I only need to replace a broken closer arm, not the whole closer. Is the Sargent 281-O-EN-TB the right order?
No. The Sargent 281-O-EN-TB is a complete surface closer with a full size iron body, 1-1/2 inch piston and standard arm, ordered when the whole unit is being installed or replaced. For an arm-only repair, the comparable set includes arm components such as the LCN 4000T-3077T standard arm replacement component and the LCN 1260-3077 regular arm with parallel arm bracket assembly. Match the arm to the closer body already on the door before ordering.
8) My door is center hung on a floor pivot. Is a Sargent 281 surface closer the right choice?
The Sargent 281-O-EN-TB is a surface-applied closer mounted to the door and frame face with thru-bolts, so it suits doors on conventional butt hinges. For a center hung door on a floor pivot, the Falcon OHC100A-DP center hung floor pivot with end load arm is built for OHC100A Series overhead concealed closers, which is a different mounting approach entirely. Confirm the door hanging method before choosing.
9) Will a Sargent 281 closer work outdoors in cold weather without reseasonal adjustment?
It is filled with all-weather fluid, which keeps closing speed stable in extreme heat and cold so you are not going back to readjust with the seasons. That is the reason it gets specified on exterior entries in northern climates.
10) Is the Sargent 281 heavy duty enough for a school or hospital entrance?
It is built for that traffic. Full size iron closer body with a 1-1/2 inch diameter piston and a heavy duty mounting bracket, rated heavy duty and Grade 1 for commercial use. Typical applications include educational, healthcare, government, retail, and multi-tenant residential openings.
11) Will the Sargent 281 closer survive someone throwing the door open hard?
It has standard pressure relief valves on both the opening and closing cycles. When the door gets slammed open past the closer's design range, the valve dumps pressure rather than letting it drive through the seals, arm, and mounting screws. On a wind-loaded exterior door or a high-abuse corridor, that is the feature that keeps you from replacing closers every year.
12) Does the Sargent 281 hold the door open?
No. As furnished with the regular arm, the 281 is a closing device only, with no hold-open function. If you need the door to stay open at a set angle on a non-fire opening, that calls for a hold-open arm such as the LCN 1250-3049/PA or LCN 4010-3049 with adjustable elbow, on their matching closer series. Never add hold-open to a labeled fire door unless it is an approved electrified hold-open tied to the alarm.
13) The Sargent 281 has to mount on the push side with a dead stop. What arm assemblies cover that?
The Sargent 281 closer body is non-handed and supports standard, top jamb, parallel and track mounting, so the body itself is suitable for push-side work; the 281-O-EN-TB ships with a regular arm rather than a parallel arm. Parallel arm assemblies in the same family of parts include the Falcon SC60A-3049DS hold-open dead stop parallel arm assembly and the Falcon SC70A-3049/PA hold open arm with PA bracket. Each is built for its own closer series, so verify the closer body on the opening.
14) Will the Falcon 8230-3077PLCM arm work with a Sargent 281 closer?
Treat them as separate systems. The Falcon 8230-3077PLCM is a standard arm with track built for Falcon 8200 Series automatic door operators, while the Sargent 281-O-EN-TB is a manual surface closer with its own standard arm and thru-bolt mounting. An operator arm and a manual closer arm are not interchangeable, so order arm hardware matched to the unit on the door.
15) Can I standardize my whole building on the Sargent 281?
That is a reasonable standardization play. One non-handed body covers left and right doors, one part number covers sizes 1 through 6 so interior and exterior openings use the same closer adjusted differently, and it mounts regular, top jamb, parallel, or track depending on what each opening allows. That reduces the closer stock you carry to a single line item plus the mounting hardware for the configuration you need.
16) What finish does the Sargent 281-O-EN-TB come in?
Sprayed aluminum enamel (EN), the standard painted finish on commercial closers. It reads as a flat silver-grey and blends with aluminum storefront and mill-finish frames, which is why it is the usual pick on back-of-house and utility openings where the closer is not meant to be a design element.
