Skywalker Cable Feed-Through Bushings White 100-Pack

Skywalker Single Feed-Through Cable Bushings are white ABS grommets sold in a pack of 100 that protect and seal low-voltage cables passing through walls when used with silicone or caulk.

These feed-through bushings provide a neat, durable solution for routing low-voltage wiring through interior and exterior wall openings before final connectors are attached. Molded from impact-resistant ABS, each bushing slips into a small pre-drilled hole to shield cables from abrasion and to help keep pests and moisture out when combined with a suitable sealant. They are sized for round, non-terminated cables and are commonly used in security, audio/visual, and low-voltage electrical projects.

How do these bushings protect cables during and after installation?

The bushings create a smooth, rigid barrier between the cable and rough hole edges so wires are not cut or worn over time. When sealant is added around the outside, the assembly also limits insects and moisture from entering the wall cavity. These are intended for use with plain cable runs, not cables that already have attached connectors.

• Rounded inner lip prevents chafing of cable jackets during movement.
• Rigid ABS resists cracking from impact or vibration.
• Sealant-compatible design supports a weatherproof perimeter.
• Not suitable for pre-terminated cables with bulky ends.

What hole size and cable types are compatible with these grommets?

Each bushing is designed to fit into a 7/16" to 1/2" pre-drilled hole and accepts most small-diameter, low-voltage conductors such as coax, speaker, CAT5/CAT6, and similar round cables. They work best with un-terminated cables that can pass through the center before final terminations or fittings are attached.

• Requires a 7/16"–1/2" drilled opening for a snug fit.
• Ideal for small round low-voltage cables (data, speaker, coax).
• Not for cables with pre-attached connectors or large fittings.
• Pack quantity supports projects requiring many feed-through points.

Are these bushings suitable for outdoor use and pest prevention?

The bushings themselves are made from weather-resistant ABS that tolerates outdoor exposure, but they reach full weatherproof and pest-resistant performance only when combined with a silicone or caulk sealant around the outside. Use a compatible exterior-grade sealant to create a long-lasting barrier against moisture and small animals.

• ABS construction stands up to UV and temperature variation.
• Use silicone or other exterior caulk (sold separately) to seal gaps.
• When sealed, helps block insects and small rodents from wall cavities.
• Not a substitute for heavy-duty rodent-proof bulkhead fittings.

Who is this for: installers, DIY homeowners, and contractors who need an economical, reliable way to route multiple low-voltage cables through walls without risking abrasion or drafts. The 100-piece pack is tailored for larger installations like multi-room AV systems, security camera deployments, or structured-cabling jobs where many neat entry points are required. Choose these bushings when you need a low-profile, sealant-ready feed-through solution for plain cable runs.
