LCN 4110-TBSRT 689 – Frequently Asked Questions

1) What is the LCN 4110-TBSRT screw pack actually used for?
It is the mounting hardware pack for LCN 4110 Series door closers: thru bolts plus self-reaming and self-tapping screws. The thru bolts pass through the door and clamp the closer or shoe from both faces, which is what you use on hollow metal or mineral-core doors that will not hold wood screws under closer load. The self-reaming/tapping screws cut their own threads, so no separate drill-and-tap step on metal doors or frames.
2) Do I need thru bolts, or will the standard screws that ship with the closer work?
Depends on the door. Standard sex-nut/screw mounting is fine on a solid door with adequate backing. Go to the 4110-TBSRT thru bolt pack when the door is hollow metal with thin skins, has no reinforcement at the closer location, or is in high-traffic service where screws pull out over time. Thru bolting spreads the closer's load across both faces instead of relying on the door skin alone.
3) Will the 4110-TBSRT thru bolt pack fit closers other than the LCN 4110?
It is sold as the 4110 Series pack and that is the fit we state. If you are mounting a different LCN closer family, order the thru bolt pack listed for that series rather than assuming this one carries over.
4) What finishes do the LCN 4110 thru bolts come in, and how do I match my closer?
Six: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Pick the same number as the closer body so the exposed bolt heads on the pull side of the door don't stand out. 689 aluminum is the default on most painted LCN closers.
5) Do I have to order anything else to mount an LCN 4110 closer with this pack?
The pack covers the thru bolts and self-reaming/tapping screws for the closer mounting. What it does not include is the closer itself, the arm, or any drop plate or bracket your opening needs when the frame face or door top rail is too narrow for a standard template. Sort the mounting position out against the closer template first, then add the plate separately if the template calls for one.
6) Is this hardware rated for commercial and institutional use?
Yes. The pack is specified for commercial rather than residential service and is described as Grade 1 for heavy-duty door control applications, which is the usual call-out for schools, hospitals, government buildings, and multi-tenant properties.
7) Does using this thru bolt pack affect ADA compliance on the opening?
The pack itself is listed as ADA compliant and supports ADA-compliant installations when used with compatible 4110 Series closers. ADA at the opening is set by the closer's opening force and closing speed adjustment, not by the fasteners, so mounting hardware won't compromise it as long as you mount the closer in the position its template calls for.
8) Can one property manager stock a single thru bolt pack across a whole building of LCN closers?
Only where the closers are 4110 Series. Stock the finish that matches the majority of your openings and keep a second finish on hand if your bronze and aluminum doors are mixed, since the bolt heads are visible on the opposite door face.
