Pass & Seymour STB Series Liquid-Tight Strain Relief Connector

Pass & Seymour STB Series Liquid-Tight Strain Relief Connector

The Pass & Seymour STB Series Liquid-Tight Strain Relief Grip is a male conduit grip engineered to connect liquid-tight flexible conduit to electrical enclosures while preventing conduit pullout. This family is available in trade sizes ranging from 1/2" through 1-1/4", giving electricians a consistent, code-compliant grip solution across a range of conduit diameters. Every STB Series grip is woven of stainless steel mesh with zinc plated steel or malleable iron bodies and nuts for corrosion resistance, and each is supplied with an insulated throat that protects conductor insulation against damage from flexing, heat expansion, and contraction. Backed by UL and CSA listings, this grip is built for demanding motor and enclosure wiring applications where liquid-tight conduit is subject to motion or strain.
