The latch post has a body, a neck, and a tip with the tip being larger than the neck. The test adapter has a frame and an engagement assembly. The engagement assembly has a drive shaft having first and second ends, a drive knob connected to the first end of the drive shaft, a drive nut connected to the drift shaft near the second end of the drive shaft. The drive nut has a threaded interior portion. The drive assembly further has a drive screw and a drive screw housing. The drive screw has a threaded exterior portion such that the threaded exterior portion of the drive screw engages with the threaded interior portions of the drive nut. A spring extends from the drive screw longitudinally away from the threaded portion of the drive screw. The spring has an enlarged portion at its distal end for gripping the neck of the latch post. Rotation of the drive shaft draws the springs and latch post into a position in which the springs are held in closed position firmly gripping the latch post.
