LCN 4040XP-TBSRT-689 – Frequently Asked Questions

1) What are LCN 4040XP thru bolts used for?
They're the mounting hardware for LCN 4040XP Series door closers. Thru bolts pass all the way through the door and clamp from both faces instead of relying on screw threads in the door skin alone, which is what you want on a heavy commercial door where the closer is under constant load. The 4040XP-TBSRT pack pairs those bolts with self-reaming and tapping screws, so the fasteners cut their own threads and you skip a separate drilling and tapping step at the opening.
2) Will the 4040XP-TBSRT kit work with other LCN closers, or only the 4040XP?
It's built for the LCN 4040XP, part of the 4000 Series. If you're mounting a different LCN closer, order the thru bolt pack called out for that model rather than assuming this one carries over.
3) Is this a door closer or just the mounting hardware?
Mounting hardware only. The 4040XP-TBSRT is a pack of thru bolts and self-reaming, self-tapping screws; the closer body, arm, and cover are separate. If you're replacing a whole unit, you're ordering the 4040XP closer itself and this pack alongside it.
4) Is there an equivalent door closer accessory kit for a Cal-Royal 900 Series closer instead of an LCN 4040XP?
No. The LCN 4040XP-TBSRT thru bolts with self-reaming and tapping screws are made for LCN 4040XP Series door closers, and the mounting hole pattern and fastener sizing follow that closer body. If the opening carries a Cal-Royal closer, the matching accessory hardware is the Cal-Royal 900 Series Door Closer Accessories Kit, which is built to the 900 Series. Order the kit that matches the closer already on the door rather than crossing brands on fasteners.
5) Do I need thru bolts on a hollow metal or aluminum door closer install?
Thru bolting is the standard call when the door face can't hold a machine screw on its own, hollow metal and aluminum being the usual cases, and on any high traffic opening where the closer gets worked hard. The 4040XP-TBSRT gives you that mounting method for the 4040XP without needing to source loose fasteners. The self-reaming and tapping screws in the pack handle their own thread cutting, so a crew doing several doors isn't tapping each hole first.
6) What finishes do LCN 4040XP thru bolt kits come in so they match the closer?
Six finishes: 689 aluminum painted, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 606 satin brass. Order the pack in the same finish code as the closer body and cover so the exposed fastener heads don't stand out. 689 and 695 are the two you'll see most often on commercial openings.
7) Does using thru bolts affect ADA compliance on a door closer install?
The fasteners don't change the opening force, which is what ADA turns on; that's set by the closer's spring size and adjustment. The 4040XP-TBSRT is rated for ADA compliant applications and supports an ADA compliant 4040XP installation. Mounting it solidly matters because a loose closer shoe lets the arm geometry shift, and geometry is what your opening force depends on.
8) What else could I buy if I need door closer accessories for a brand other than LCN?
Closer accessories are brand and model specific, so the match depends on what closer is on the door. For Cal-Royal 900 Series closers there's the Cal-Royal 900 Series accessories kit. On the arm side, Deltana carries the DCCA4041 cushion arm for its DC40 closer and the DCHA1050 hold open arm for the DC10, and Dormakaba offers a 1-1/2 inch offset bottom arm with cover under 15323. None of those interchange with an LCN 4040XP; the 4040XP-TBSRT is the pack for that closer.
9) Will a Deltana DCCA4041 cushion arm work in place of LCN thru bolts?
No, those solve different problems. The 4040XP-TBSRT is mounting hardware: thru bolts and self-reaming, self-tapping screws that fasten the closer to the door or frame without pre-drilling. The Deltana DCCA4041 is a cushion arm for the DC40 door closer, and the Deltana DCHA1050 is a hold open arm for the DC10 closer. Arms control how the door swings and stops; thru bolts control how the closer is held to the door. A closer replacing an arm still needs its own fasteners.
10) What is the difference between the LCN 4040XP thru bolt kit and a Dorma 15323 offset bottom arm?
The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part with no fire rating, and it connects a floor closer spindle to the bottom of the door. The LCN 4040XP-TBSRT is commercial-grade thru bolt and self-tapping screw hardware that anchors an LCN 4040XP surface closer in place, and it supports ADA compliant closer installations. If a bottom arm is bent or the cover is missing, the 15323 is the part to look at; if the closer body itself is loose or being remounted, the thru bolt kit is what the job calls for.
11) Is this fastener kit rated for commercial use or is it a residential-grade part?
Commercial. The 4040XP-TBSRT is specified for commercial door control applications, which is where you find the 4040XP anyway: office buildings, schools, hospitals, retail, warehouses, government facilities, and multi-tenant residential common doors.
12) I'm standardizing closers across a building. Should I thru bolt every door or only some?
Thru bolt the openings that take abuse and any door whose face won't reliably hold a machine screw, which on most commercial buildings means the hollow metal exterior and stair doors before the light interior ones. Specifying the 4040XP-TBSRT pack alongside each 4040XP keeps one fastener method across the fleet, so your maintenance crew stocks one part instead of matching whatever went in door by door. Order the pack in the finish that matches the closers you standardized on.
13) Which door closer accessory kit should I standardize on across a building with mixed closer brands?
Installation accessory kits follow the closer, not the building. Doors running LCN 4040XP Series closers take the 4040XP-TBSRT thru bolts with self-reaming and tapping screws, available in 689 aluminum painted, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 606 satin brass to match the closer covers already in place. Doors running Cal-Royal 900 Series closers take the Cal-Royal 900 Series accessories kit. If the goal is one part number across the facility, standardize the closers first and the accessory kit follows.
