Spring loaded Latches

There are over 60,000 Hop-Lok latches presently in use on farms, ranches, auction barns, breeding facilities and veterinary hospitals. This latch is unconditionally guaranteed against breakage for life. The latch should last a lifetime with only an occasional lubrication of the plunger and housing. The plunger is made of cold-finished machine steel, the actuating spring is stainless steel, the knob is aluminum alloy and the housing is made of drawn-over-mandrel steel tubing.
