Meet the Jandorf 5/8 in. Rubber Bushing (2 pk) — a practical, high-value solution for insulating and protecting cables as they pass through panels, boxes, and enclosures. Crafted from durable rubber, this two-pack guards against edge wear, provides reliable insulation, and helps you maintain a clean, professional install.
Designed for 5/8 in. trade-size openings, these bushings feature a precise inner bore of 3/8 in to accommodate conductors up to that diameter while the 15/16 in outer diameter protects the surrounding material and shields wiring from sharp edges. With a wall thickness of 0.38 in, the rubber bushing delivers solid abrasion resistance and dependable cushion where cables meet a panel knockout.
Why this Jandorf bushing stands out
-
Two-pack convenience — keep spares on hand for quick repairs and future projects.
-
Carded packaging for easy retail display and quick identification in your shop or on-site kit.
-
Insulating rubber — reduces conductor wear and helps create a tighter, cleaner seal around wires.
-
Precise dimensions — inner bore 3/8 in, outer diameter 15/16 in, and wall thickness 0.38 in, tailored to a 5/8 in trade-size opening.
-
Reliable material provides enduring performance in everyday electrical installations where edges and sharp surfaces are a concern.
Ideal uses and applications
- Electrical enclosures, control panels, and junction boxes that require a 5/8 in bushing to protect conductors as they pass through knockout holes.
- Wiring setups that demand an insulating barrier between cables and metal edges to prevent abrasion and insulation damage over time.
- Quick upgrades or replacements in existing installations where a compact rubber bushing is the right fit for small-diameter cables.

Smart installation tips
Match the inner bore to your conductor size (up to 3/8 in) and press the bushing into the knockout until it sits flush against the panel surface. Route the cable through the bore, ensuring a smooth pass without sharp bends. For a tidy finish, confirm the outer edge sits evenly against the panel to help minimize dust and debris entry around the opening.
