LCN 4110-TBTRX 689 – Frequently Asked Questions

1) What is the LCN 4110-TBTRX screw pack used for?
It's the mounting hardware kit for LCN 4110 Series door closers: thru bolts plus TORX drive machine screws. The thru bolts pass through the door or frame so the closer is clamped rather than held by wood or sheet metal threads, which is what you want on a high traffic opening where sex bolts are specified or where the substrate won't hold screws on its own.
2) Will the 4110-TBTRX thru bolt pack fit closers other than the LCN 4110?
It is sold as 4110 Series hardware and nothing else is stated as compatible. If you're mounting a different LCN series closer, order the thru bolt pack built for that series rather than assuming this one crosses over.
3) Why TORX screws instead of Phillips on a door closer?
Two reasons. TORX transfers torque without camming out, so you can pull the closer body down tight without chewing the head. And it deters casual tampering in public areas, which is the usual reason a spec calls for TORX on closers in schools, lobbies, and restrooms.
4) What finishes does the LCN 4110 TORX thru bolt pack come in?
Thirteen: 616 satin bronze blackened, 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Match the screw finish to the closer cover so the fasteners disappear into the installation.
5) Do I need anything else to mount the closer besides this kit?
The pack covers the fasteners: thru bolts and machine screws for the closer installation, so you aren't chasing hardware mid-job. The closer body, arm, and any drop plate or bracket the opening requires are separate items.
6) Can I use thru bolts on a hollow metal door for a 4110 closer?
That's exactly the case thru bolts address. Rather than relying on threads tapped into thin sheet steel or on a hollow core, the bolt runs through the door and clamps from the far side, so the pull-off load is carried by the whole leaf. If your opening has solid reinforcement already, standard machine screws are the simpler route.
7) Is this hardware suitable for commercial and ADA openings?
It's a commercial grade kit, listed ADA compliant when used with compatible 4110 Series door controls. Property managers standardizing closers across offices, schools, healthcare, retail, or multi-tenant buildings can spec the same pack on every opening and just change the finish.
