This is the fastest, easiest way to automatically form locks in your rubber molds! Pack your mold normally, then push one of these solid stainless steel pins into each corner of the mold before vulcanizing.
These are 23mm pins for use with 1-1/8" to 1-1/2" thick molds. After vulcanizing, pull out the pins to cut your mold - but don’t worry about cutting locks. Rubber Mold Locking Pins make perfect locks; there is no shifting of the mold halves during wax injection.
Sold in sets of 4 pins.
