A heavy duty spacer must withstand heavy vertical compression from backfill soil, concrete pours, and surface vehicle traffic. Modern spacer designs distribute downward forces evenly across all connected conduits, preventing deformation of sensitive electrical lines. Using robust spacers prevents structural shifts during the pouring of concrete envelopes. Proper alignment maintains the internal diameter of each duct, allowing smooth cable pulling without snagging. High load capacity ensures long-term safety and stability for high-voltage power lines and critical telecommunication grids buried beneath busy highways.
