Stone Stopper Orange Liner

Stone Stopper Orange Liner

This Stone Stopper is a replacement urethane liner for the rock blocker assembly on rear discharge concrete mixers. Mounted on the main chute, the rock blocker (or stone stopper) acts as a guard to prevent stones and large aggregate from spilling during transit or pouring. This durable, orange polyurethane liner provides an abrasion-resistant surface that withstands the harsh environment of concrete work. It is a critical replacement part for maintaining safety and preventing material loss on McNeilus, Con-Tech, and other compatible mixers.
