A typical heavy-duty HDPE Duct Spacer features modular interlocking mechanisms, rib reinforcements, and precisely sized circular cutouts to accommodate standard conduit outer diameters. The interlocking side tabs on an HDPE Duct Spacer allow field technicians to connect multiple units vertically and horizontally without needing specialized tools, building custom duct configurations instantly. Internal reinforcement ribs built into the HDPE Duct Spacer distribute vertical loads evenly across the assembly, enabling it to withstand heavy overburden soil pressures. Furthermore, many designs of an HDPE Duct Spacer include integrated rebar securing slots, enabling installers to tie the spacer frame to steel rebar cages when constructing concrete-encased duct banks. These combined design characteristics give an HDPE Duct Spacer the versatility and load-bearing capacity required for complex underground projects.
