Rock Anchor

Rock Anchors are installed into core holes bored into rock. The Rock Anchor is tightened along the anchor shaft to expand the resistance wedges into the rock.

Description

Installed into solid, unweathered rock and expanded to develop the full strength of the anchor rod. Each anchor features a triple eye for up to 3 guy connections. A hole size, as listed below, is drilled into the rock to a minimum of 12” in line with the guy angle. The anchor is then placed into the hole and a bar through the eye is used to turn the rod and expand the anchor wedges into the rock. Rod is galvanized per ASTM A123, the wedges are coated in a rust inhibitor.
