LCN 4040XP-3077-695 – Frequently Asked Questions
1) Will the LCN 4040XP-3077 arm work on a left hand door and a right hand door?
The 4040XP-3077 regular arm is non-handed, so the same part goes on either hand with no modification and no field conversion. For a property manager stocking a building, that means one arm number covers every door in the fleet regardless of swing direction.
2) Can I use the 4040XP-3077 arm to replace a broken arm on an LCN 4041 closer?
Yes. The 4040XP-3077 is a replacement regular arm for LCN 4000 Series closers, including P4041 systems. If the closer body on the door is a 4000 Series unit and it was installed with a regular arm, this is the direct swap. If the existing installation uses a parallel arm bracket on the push side of the door, this arm is not the right part.
3) Which side of the door does a regular arm door closer arm mount on?
Regular arm mounting puts the closer on the pull side of the door, or on the top jamb in a shallow reveal condition. The arm projects out from the door face when the door is closed, which is why some jobs go parallel arm instead to keep the hardware tucked against the door. If your opening has the closer body on the push side, you need a parallel arm assembly, not this one.
4) My office door slams at the end of its swing. Does the LCN 4040XP-3077 arm help with that?
That is what the adjustable impact reduction on this arm is for. It softens the door's travel at the end of the swing, which cuts the bang and the wear on the frame and hinges in a high traffic opening. It's field adjustable, so you tune it on the door rather than ordering a different part.
5) Is the LCN 4040XP-3077 closer arm ADA compliant for a healthcare or school opening?
The 4040XP-3077 is listed ADA compliant and rated for commercial applications including office, healthcare, education, and multi-family. Worth knowing that ADA opening force is set by the closer body's spring size and adjustment, not by the arm alone, so the closer itself has to be adjusted to the required force on the opening.
6) What finishes does the LCN 4040XP regular arm come in for matching existing hardware?
Nine finishes: 616 satin bronze blackened, 633 satin brass, 639 satin bronze, 651 bright chrome, 689 aluminum, 693 gloss black, 695 dark bronze, 696 brass, plus an Aluminum SRI special rust inhibitor option. The 689 aluminum is the common commercial default. If the arm is going somewhere damp or exterior facing, the Aluminum SRI is the one built for corrosion resistance.
7) Do I need to order a whole new door closer or can I just replace the arm?
Just the arm, if the closer body is sound. The 4040XP-3077 is sold as a replacement part for LCN 4000 Series closers, so a bent or seized arm on an otherwise working closer is an arm-only order. A closer that is leaking oil or will no longer hold an adjustment is a body problem, and no arm fixes that.
8) Will an LCN 4000 Series regular arm work on a door with a deep reveal?
Top jamb mounting with this arm is for shallow reveal conditions. On a frame with a deep reveal, the regular arm geometry runs out of room and you need a different mounting approach or a bracket built for that reveal. Measure the reveal from the face of the door to the face of the stop before ordering.
9) What do I have to specify when ordering an LCN 4040XP-3077 arm?
Finish is the only choice to make. The arm is non-handed, so there is no left hand or right hand to call out, and the mounting is fixed as regular arm. Pick the finish that matches the closer and the rest of the door hardware and that completes the order.
