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.

Specify your current closers model number when ordering. Not all of the LCN closers have the same shape spindle on the door closer cylinder. Model Available here are the:

The LCN 1370 was a door closer made in the late 1990's to 2006 or so. The closer had a special mounting plate that made installation very quick. 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. 

These standard metal extensions can be used with the LCN SEM magnet door holders to increase the holder projection. The treads on this piece are 3/8-16.
