This economical but powerful system is comparable to our competition’s standard system. Available in pin style only.

Eraser PQ™

The Eraser PQ (Pit and Quarry) system is an economical cleaner designed for performance and reliability. With a simple and effective spring tensioning unit, it uses our 6″ tall Raptor blade and requires little to no maintenance.

It is equipped with a 7.25″ tall Raptor blade, and can handle most of your demanding applications with ease. Available only with Safe Torque™.
