1 Hole Barrel Cushions

Shop 1-hole barrel cushions for supporting individual cables within compatible hangers, clamps, and cable blocks. Also called single-hole cable inserts, hanger grommets, and adapter grommets, these components help organize coaxial, fiber, hybrid, and power cables throughout telecom and broadband installations.

Each 1-hole barrel cushion contains a single opening designed for a specific cable outside diameter or diameter range. Matching the insert to both the cable and surrounding hanger helps provide the intended fit within the cable-support assembly.

This collection includes standard cable inserts, heavy-duty inserts, hybrid cable grommets, and hanger adapter grommets. For additional cable-support configurations, explore our complete selection of barrel cushions, including single-hole, multi-hole, and universal cable inserts.

When multiple cables must be supported within one opening, browse our multi-hole barrel cushions. These inserts provide multiple openings for organizing compatible coaxial, fiber, hybrid, or power cables within a shared support assembly.

Single-hole cable cushions are commonly used with snap-in, click-on, and butterfly-style cable supports. Pair compatible inserts with our telecom cable hangers for installations on towers, monopoles, rooftops, DAS networks, small-cell sites, broadband systems, and equipment shelters.
