Base Duct Spacers

Base Duct Spacers accurately separate ducts while locking them firmly together and mainly used at the ground floor of your application. Base spacers are used to give space under pipes to avoiding resting directly on the ground and keeps them in line. Our most popular sizes are offered with unique rebar holder slots for quick reinforcing bar installation and the bases have support holes for securing the base spacers to the trench bottom. Duct Spacers make alignment of duct banks easy by allowing more room to work. These spacers are also ideal for concrete burial applications providing plenty of room for concrete to settle around each individual pipe. Intermediate Spacers are available in multiple sizes and package quantities.
