Stone Stopper Latch Pin

Stone Stopper Latch Pin

This is a replacement latch pin for the rock blocker, also known as a stone stopper, assembly on a concrete mixer truck's discharge chute. The rock blocker is a safety device that pivots over the chute opening to prevent stones and debris from being ejected during transit. This pin is a critical component of the latching mechanism that holds the blocker securely in place. It is essential for routine maintenance or replacement when the original pin is worn, bent, or lost, ensuring the safety device remains fully operational.
