Stone Stopper Urethane Liner

Stone Stopper Urethane Liner

This black rock stopper liner is designed for use in the chute systems of rear discharge concrete mixer trucks, including McNeilus, Con-Tech, CBMW, and Kimble models. Positioned within the foldback or main chute assembly, the liner flexes to allow concrete to flow during a pour but blocks loose rocks and material from escaping while the truck is in motion. Operators typically replace this liner when the original part becomes torn, brittle, or worn down from the highly abrasive nature of concrete aggregate. Manufactured from high-wear polyurethane, it provides excellent tear resistance and helps prevent road hazards.

Key Features

• Manufactured from high-wear, abrasion-resistant black polyurethane
• Flexible design allows unobstructed concrete flow while blocking loose aggregate
• Reduces cleanup time and prevents road hazards by containing material during transit
