The expanding rock anchor is a big time, labor, and money saver.This anchor expands and wedges against solid walls of rock. And, once it is expanded, the harder the pull on the rod—the tighter it wedges. Wedges are made of malleable or ductile iron with a rust-resistant coating. Rod should be in line with the guy.

Installation

Installation is quick and simple. Bore the hole with hand or power drill, making sure that the diameter of the hole is 1⁄4-inch larger than the diameter of the unexpanded anchor. Drop the anchor in the hole. Put a bar through the large eye of the anchor rod. Turn the rod until the anchor is firmly expanded against the sides of the hole. Grouting should be done if protection of the rock against weathering is a concern.
