1/2X2 1/4 Rod Hanger Sleeve Anchor Zinc (Pack Qty 25) BC-5036ASLRH

The anchor works by expanding against the material in which it is embedded. When the hex nut is tightened the conical end is pulled into the dilating sleeve pushing it outward 360° around the anchor into the masonry. They are used to attach threaded rod to cinder block, marble, concrete or thin wall. One advantage of the sleeve anchor is that it can be removed after it's been installed. Another is that the length of the sleeve induces less stress on the substrate than does a wedge anchor Anchors should be installed with a minimum of 10 anchor diameters between each other and a minimum of 5 diameters from the edge
