Engineered for quick assembly and structural rigidity, an HDPE Duct Spacer typically features interlocking side keys, vertical stacking grooves, and durable locking pins. These design elements allow utility crews to connect multiple spacer units vertically and horizontally to build customized duct banks tailored to project specifications.
