LCN 4110T-159 689 – Frequently Asked Questions

1) What is the LCN 4110T-159 and which door closers does it fit?
The 4110T-159 is the arm screw for LCN 4110T Series door closers, the fastener that holds the closer arm assembly together at the mounting point. It is a series-specific part: it is the arm screw for the 4110T, so if the closer on your door is a different LCN family, order the arm screw for that family instead.
2) What finishes does the LCN 4110T arm screw come in so it matches my closer?
Six finishes, and they follow the standard LCN closer finish codes so the screw disappears into the arm: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Match the code stamped on or specified for the closer you are servicing rather than eyeballing the color, since 690, 691 and 695 all read as bronze from a few feet away.
3) Can I just use a hardware store machine screw instead of the LCN arm screw?
Not a good swap. The 4110T arm screw is a commercial door closer component built for the 4110T arm assembly, and it is also finished to the closer's finish code (689 through 696) so the head matches. A generic fastener will not carry the finish, and getting the wrong size at the arm pivot is how arms work loose and closers get pulled off doors. Order the series part.
4) I maintain a building with LCN 4110T closers on ADA openings. Does replacing the arm screw affect ADA compliance?
No, provided you rebuild the closer with the correct parts. The 4110T-159 is an ADA compliant component used with compatible LCN closer systems, so a like-for-like arm screw replacement keeps the opening as it was specified. What actually controls compliance on that door is the closer's opening force and closing speed adjustment, so re-check the sweep and latch settings after you reassemble the arm.
5) My LCN 4110T closer arm keeps coming loose at the joint. Do I need a whole new arm?
Often not. The arm screw is the fastener that secures the 4110T arm assembly, and a worn, stripped or missing screw is a common reason an arm loosens at the pivot. Replacing the 4110T-159 restores the connection without buying a new arm or closer body. If the arm itself is bent or the holes are elongated, then the arm has to be replaced too.
6) Is the LCN 4110T arm screw suitable for a school or hospital door, or is it a residential-duty part?
Commercial duty. The 4110T-159 is specified for commercial door control service, and the 4110T closers it serves are used in offices, schools, healthcare facilities, retail, warehouses, multi-tenant residential and government buildings. If you standardize on 4110T closers across a facility, this is the arm screw to stock for all of them.
