Klyyo Clyro Round Cable Gland Waterproof Split-Seal, Black, 2.5 x 0.79" UV-stable

The Klyyo Clyro 2-set round cable glands are waterproof split-seal pass-throughs that protect cables and connectors on boats, RVs, and outdoor enclosures without removing the cable ends.

These compact marine-grade cable glands are designed to keep water, dust and salt spray out of critical cable entry points while accommodating thick cables and attached connectors. Built from UV-resistant plastic and 316 stainless steel fasteners, each 2.5" diameter gland accepts cable diameters up to 1.08" (27.5 mm) and connector heads up to 1.38" (34 mm). The split-seal design speeds installation because you don’t need to thread connectors off—simply position the gland around the cable and secure it in place.

How do these cable glands install without disconnecting my cables?

The glands feature a split-seal body that opens around existing cables and connectors, eliminating the need to remove plugs during assembly. Installation requires drilling a matching hole, seating the gland and fastening it with the supplied screws and anchors.

• Split-seal body fits around installed cables and connectors for fast retrofits
• Includes 8 locking screws, 8 anchor screws and 8 drill tubes for accurate placement
• 2.5" diameter standard makes aligning and cutting holes simpler

Will these withstand saltwater and UV exposure on a boat?

Yes — the parts that contact the environment are made from durable marine-grade plastic while all metal fixings are 316 stainless steel. That combination resists corrosion from seawater and degradation from sunlight so the seal remains reliable in harsh marine conditions.

• 316 stainless steel fasteners resist rust in saltwater environments
• UV-stable plastic body resists cracking and discoloration
• Designed for repeated outdoor exposure on boats, RVs, and panels

What cable and connector sizes are supported by this gland set?

Each round gland accepts cables up to 1.08" (27.5 mm) in diameter and accommodates connector heads up to 1.38" (34 mm). The compact 2.5" diameter housing works with common wiring runs while leaving enough room for a secure, watertight seal around bulkier connectors.

• Cable capacity: up to 27.5 mm (1.08") diameter
• Connector head allowance: up to 34 mm (1.38") diameter
• Gland size: 2.5" diameter × 0.79" height for standard mounting holes

What comes in the box and what should I watch for during installation?

The package contains two round cable glands plus an installation kit of screws and drill tubes sized to help create precise holes and anchor points. Be mindful of the small parts: keep them away from children and pets, follow drill diameter recommendations, and allow for slight measurement tolerances during mounting.

• Includes 2 glands, 8 locking screws, 8 anchor screws and 8 drill tubes
• Follow hole-sizing guidance and use supplied drill tubes for accuracy
• Keep small parts away from children; allow minor size variances

Who is this for: The Klyyo Clyro 2-pack round cable glands suit boat owners, RV builders, solar or outdoor lighting installers, and DIYers who need a tidy, watertight pass-through that accepts pre-terminated cables.
