Locking gas springs incorporate a mechanism to enable the rod to be locked at any point in its travel. This mechanism is actuated by a plunger that protrudes from the rod. When this plunger is depressed the rod is free to operate as normal. When the plunger is released, which may be at any point in the stroke, the rod is locked in that position.
Locking Rails support rope locks and the index cards used to identify sets. The rope locks and index cards are mounted on a 3″x 5″x 1/4″ formed steel angle. It is built to withstand a 300 lb per linear foot up load. Two angles are provided to support 855M floor blocks.
