LCN 4040XP-61 Blade Stop Spacer

The LCN 4040XP-61 is a blade stop spacer for the LCN 4040 and 4040XP series surface door closers. Its job is specific and easy to miss: it lowers the parallel arm shoe so it clears a 1/2 inch (13mm) blade stop on the door frame. If you're mounting a 4040XP parallel-arm and the arm shoe is hitting or sitting too close to a blade stop, this is the part that solves it. It's an optional accessory, needed only on openings with that particular frame condition, and it's non-handed so one spacer works regardless of door swing.

When you need the 4040XP-61 blade stop spacer

A blade stop is the raised lip on some door frames that the door closes against. When you mount a 4040XP closer in the parallel-arm configuration, the arm shoe attaches to the frame face, and on a frame with a 1/2 inch blade stop, the shoe can sit too high to clear it cleanly. The 4040XP-61 spacer drops the parallel arm shoe down by the needed amount so the arm seats and operates correctly. Without it, the arm geometry is off and the closer won't perform the way it should.

So the simple rule: if your 4040 or 4040XP is parallel-arm mounted on a frame with a 1/2 inch blade stop, you likely need this spacer. If your frame has no blade stop, or the closer is regular-arm mounted on the pull side, you don't. When in doubt, check the frame condition before ordering, because this is an add-on part, not something that ships with the closer by default.

Why order the right closer parts the first time

The 4040XP is LCN's heavy-duty workhorse, and a closure that lasts decades is worth keeping properly fitted with the correct parts. A blade stop spacer is inexpensive next to the closure itself, but skipping it on a frame that needs one leaves the arm geometry wrong, which shows up as a closure that doesn't latch or close cleanly. Getting the small parts right is what keeps the whole assembly working as designed.

If you're servicing or installing a 4040XP and aren't sure which arm, bracket, or spacer your opening calls for, it helps to identify the mounting type and frame condition first. The same closer mounts regular, top jamb, or parallel arm, and each has its own bracket and accessory needs.
