The main use of Drop-In anchors is to insert threaded rod to suspend electrical cable trays, HVAC ductwork and fire sprinkler pipe and heads. They can be used in applications that require a flush mounted anchor and when a bolt needs to be inserted and removed. Drop-In anchors should only be used in solid concrete.
