LCN 4630 replacement arm, LCN part # 4630-3077T

The LCN Door Closer Hold Open Arm 3049 has an adjustable nut that allows the door closer arm to lock when they reach a pre select position.  This arm can be used on most LCN Door Closers because the Hold Open function is in the arm.   If you have a regular armed LCN Closer currently, you can use this arm to make them have the Hold Open function.  Two words of warning, they can not be used on an interior fire rated door, and Hold Open arms usually break.   The manufactures sell more door closers with regular arms, but we tend to sell more Hold Open arms, meaning they wear out or break a lot easier then Regular Arms.

Specify your current closers model number when ordering.

The LCN Door Closer Hold Open Head And Tube 3048 - 3048L.  As the arm rotates the pivot point threads close on to the mounting bracket face and create a friction catch.  If yours is new, try rotating the mounting plate 180 degrees so the threads tighten as it closes. This replacement part from LCN either breaks or wears out.   The material some times wears out due to the friction of open and closing.  But the biggest issue seems to be the point where the tube mounts to the cast iron connector.

Many people have this door closer in use and now they are starting to fail. The LCN 1370-18QF Quick Fix Plate converts the mounting holes of the 1370 to a standard template closer, which is 3/4" x 9-1/16". By using this plate you will not have to redrill holes in your door. The plate measures 2 by 10-1/4 inches with tapped holes that measure 3/4 x 9-1/16 inch.
