Designed to be used with DSI pull test equipment, the pull test ring is fitted to friction bolts prior to installation. The ring allows measured load to be safely applied to installed friction bolts for the purpose of pull testing.

The DSI Friction Bolt is manufactured from high strength steel tube which has a slot along its entire legth. A ring, or collar, is welded on the outer end to hold a domed plate to the rock surface.
