LOCK+LOAD is wet-cast with high strength air entrained concrete (5500 psi) in heavy duty moulds made completely of recycled plastic. This forming system quickly produces beautiful dimensionally accurate pieces.
In addition to being inexpensive these moulds are durable...most are still in use after over 1000 cycles.
The moulds are designed to stack for easy handling, curing, stripping and dense space utilization.
