Locking device for cast iron grates in the POLYCAST 900 series frame. Part# DA0942
Grates need to be locked in place in situations where there's a possibility they will be driven over, preventing the grates from hopping. It also prevents debris from working in between the grates and channels which can ultimately damage the grates. This helps to provide system integrity when used appropriately.
