Drop-in anchor is an internally threaded, flush-mounted mechanical anchor designed for solid concrete. It consists of a cylindrical shell and a pre-assembled expander plug, delivering exceptional holding power through controlled expansion. It is ideal for overhead applications, including the suspension of HVAC ducts, pipe supports, cable trays, lighting fixtures, and others.
