Kraloy® conduit interlocking spacers are available in a variety of spacing dimensions for all conduit sizes. 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. Kraloy® conduit spacers manufactured with the rebar holder slots can accommodate a maximum rebar diameter of 5/8 in for the 2 in conduit size and 7/8 in for all other conduit size spacers. All conduit spacers provide a 3 in clearance from the trench base to the bottom of the first conduit. Kraloy® recommends the installation of a spacer every 5 to 6 ft along the raceway length to provide the proper and even support of the conduit assembly.
