Skywalker Cable Feed-Through Bushings 1/2" (100)

Skywalker Single Feed-Through Cable Bushings are 100 black ABS grommets designed to protect and seal low-voltage cables where they pass through walls.

These single feed-through bushings give a tidy, weather-resistant way to route cables through exterior and interior walls. Made from durable ABS plastic and sized for a 1/2" pre-drilled hole, each bushing shields cable jackets from sharp edges and helps block drafts, pests, and moisture when combined with silicone sealant (sealant sold separately). The pack contains 100 identical units so you can finish multiple runs or keep spares for future installs.

How do these bushings protect cables during installation?

Each bushing provides a smooth, rounded tunnel that prevents cable insulation from rubbing against raw plaster, siding, or drilled holes. That reduces abrasion and the risk of shorted conductors or signal loss over time without altering cable routing.

• Rounded inner lip cushions cable jacket contact points
• Prevents sharp edge wear from drilled holes
• Works with low-voltage conductors like coax, Ethernet, thermostat, and speaker wire

Are these bushings weatherproof and pest resistant?

The ABS material itself stands up to typical outdoor exposure, and when you apply a compatible silicone sealant around the bushing it becomes an effective weather and critter barrier. The product is described as "varmit-proof" when sealed correctly, helping keep insects and small rodents out of wall cavities.

• UV-resistant ABS housing resists cracking and brittleness
• Seal with silicone to create a water- and pest-blocking joint
• Suitable for exterior walls, soffits, and junction points

What hole size and cables are these bushings compatible with?

Each bushing is designed to be installed into a 1/2" pre-drilled hole and accommodates most low-voltage cable diameters found in home and commercial installs. They are not sized for large conduit or high-voltage cable runs; measure your cable bundle before drilling.

• Requires a 1/2" diameter pilot hole for each bushing
• Fits single or small bundled low-voltage wires (Ethernet, coax, speaker, alarm)
• Not intended for large-diameter power conduits or cable trays

How many come in a pack and what are common installation tips?

You get 100 individual bushings per pack—ideal for installers, builders, or homeowners doing multiple runs. For best results, pre-drill carefully, seat the bushing flush with the surface, and finish with a thin bead of silicone on the exterior side to seal gaps.

• Pack contains 100 black ABS bushings ready for installation
• Seat flush and use silicone sealant on the exterior face for weatherproofing
• Keep extras for repairs, retrofits, or multi-room projects

Who is this for: These Skywalker feed-through bushings are aimed at electricians, AV installers, home remodelers, and DIYers who need a reliable, low-cost method to run low-voltage cables through walls cleanly and safely. If you want a durable, weather-tolerant grommet solution for multiple cable runs or a stock item for ongoing projects, this 100-piece kit offers consistent sizing and long-term protection when paired with an appropriate sealant.
