6" Aluminum ball and socket Door catch

Two cast aluminum pieces. SUPER VERSATILE because you can change up the position of the arm in so many ways by installing the ball & socket bracket side vertical for a 180 degree arm radius (for trailer doors) or flat for the arm to hold steady in a slot for many other industry applications. The "snap/catch" side attaches to the wall of the trailer on a bracket with 4 holes. The "arms" hangs from a door-side bracket (w/2 holes) when not in use. Two hands are needed to snap the arm into the catch bracket. Also, two hands are needed to hold the catch open in order to release the arm. This door holder cannot disengage unless it is manually released, even if it is bumped or pulled. Brightly polished cast-aluminum. The 6" Ball & Socket arm will hold the door 7 1/2" away from the trailer wall. *Use six #12 sheet metal screw to fasten the Ball & Socket Door Hold Back *door side (arm) bracket holes: 2 7/16" vertical screw centers *trailer side (latch) bracket holes: 13/16" vertical, 1 5/16" horizontal screw centers
