Strain Relief Clamps

Download attachments:

 Patton & Cooke strain relief clamps eliminate strain of the cable connections at the coupler/enclosure interface on electric shovels, drills, LHD’s, jumbos, junction boxes or cable supports. Also supports a cable in vertical shaft and pole applications.

Made of thick, black polyurethane and using galvanized hardware and wire rope, the strain relief clamp is designed to prevent cable jacket damage and to withstand the tough use in typical mining, construction and utility applications.

The strain relief clamp is available in 12 sizes, covering cable diameters 0.625″-3.625″ (16-92mm). Larger sizes available on request.
