Armoured steel gland construction provides rugged mechanical protection for TECK armored cable, delivering long service life and reduced field failures in demanding environments. The 2-1/2 inch NPT thread ensures compatibility with standard fittings, enabling fast, leak-free installations and minimizing commissioning time in new builds or retrofits. Armor and outer sheath dimensional ranges (Armor 2.24-2.56 inches; Outer sheath 2.38-2.64 inches) allow precise seating and dependable sealing, which reduces ingress risk and maintenance needs in corrosive or dusty settings. Compliance is built in with NEC/CEC standards, NEC hazardous ratings (Class II, Division 1, Class III), and a NEMA 4 enclosure rating, giving buyers confidence in safety, regulatory alignment, and customer audits. The gland is designed for general purpose use with TECK armored cables, offering straightforward compatibility and a smooth installation experience, while providing a clear path to code compliance and lifecycle cost reduction. Additional installation documentation and reference sheets support installers, helping address common objections about complex fittings and field rework.
