Drill a 1/2" O.D. hole about 2" deep in a concrete or masonry surface and insert this sleeve. Then, you can thread a standard 5/16" x 2" lag screw into the sleeve for a secure friction grip in the concrete. The PVLS516 has a gradual restriction taper inside the sleeve which expands the sleeve when the lag screw is fully seated. Very useful where wood surfaces are not available to secure the dish reflector foot or wind legs.
