Drop In Anchors

(5) to (80)
(100) to (500)
Each order also includes the necessary set tool.
(1 quarter inch bolt)
A Drop-In anchor consists of a zinc plated steel tubular expansion shield and a solid, cone-shaped expander plug. The expander plug is case hardened and tempered to prevent galling and binding during expansion. To install you need to drill your holes 1 11/16" deep with a 1/2" masonry drill bit. When you drop in the anchor make sure the front of the drop in anchor sits a little behind the surface of the concrete wall. The back of the climbing holds should not touch the drop in anchors when fastened. If the anchor is sitting at the proper depth, tap the expander plug in place using a hammer and the "set tool" (small bolt) we provided. Once it's securely in place it's ready for a climbing hold to be fastened! If you have a hollow cinder block wall, you'll need Hollow set Drop in Anchors.
