Note: Torque for dome nuts was determined using a metal rod. It may vary for cable, depending on the crush resistance of the cable. We recommend to determine the actual torque empirically, using the actual cable used. The values shown are for reference only.

Note: Nylon strain relief fittings installed in a threaded connection and exposed to elevated temperature should be retained with a sealant, such as Locktite®, to avoid a loose connection when the temperature fluctuates.
