Appleton Uni-Seal Rigid Conduit Hubs deliver fast, single-wrench installation with a simple two-piece design—no welded hubs or locknuts needed. The patented hex-hub wedge adapter sits nearly flush for maximum wiring space, while a flame-resistant insulated throat provides protection without end bushings. Built-in neoprene gasket ensures watertight sealing, and the self-locking body bites into the enclosure for 360° pressure, positive grounding, and vibration-resistant performance.
