Blue Sea 3126 SMS Enclosure Large Cable Gland PG29 - #6 Cable

The Blue Sea 3126 SMS Enclosure Large Cable Gland PG29 is a heavy-duty electrical connector designed for marine, automotive, and industrial applications where large-diameter cables require secure, weatherproof entry into control enclosures. This cable gland accommodates #6 four-conductor cable and is engineered to maintain environmental sealing in demanding conditions. It serves technicians, system integrators, and equipment manufacturers who need reliable cable management solutions that prevent moisture ingress and maintain signal integrity in harsh operational environments.

Built to Blue Sea Systems' exacting marine-grade standards, the 3126 features a PG29 thread size that provides robust mechanical retention and a compression seal around #6 cable without compromising conductor integrity. The large cable gland design accommodates the substantial cross-section of four-conductor #6 wire while maintaining a compact overall footprint of 3 x 2 x 5 inches. The gland's compression-style sealing mechanism creates a watertight barrier that prevents corrosion and electrical degradation, critical for systems exposed to salt spray, vibration, and temperature cycling. Construction materials and design conform to industry standards for electrical safety and environmental protection.

This cable gland is ideal for marine electrical systems, RV power distribution panels, industrial control enclosures, and any application requiring a sealed entry point for heavy-gauge multiconductor cable. Installation is straightforward—the PG29 thread mates with corresponding enclosure knockouts, and the compression fitting secures #6 cable without requiring additional strain relief. Weighing just 0.1 lbs, the 3126 adds minimal bulk while delivering maximum reliability. Technicians and system designers rely on Blue Sea Systems components for their proven durability in saltwater, high-vibration, and temperature-variable environments where component failure is not an option.
