Split Strain Relief Clamps

Download attachments:

Advanced Entrance Fittings – The Patton & Cooke split strain relief entrance fitting is ideally suited for installations where trailing cable couplers are not being used but where cables may be installed and moved frequently.

The split design means that the entrance fitting can be installed or removed without disturbing the stress cones, sleeves or taping which makes up the cable termination for quick and easy installation and removal without any tools! Available in 6 sizes which cover cable outside diameters from 2.76-3.50 inches (70-89mm) diameters 0.625″-3.625″(16-92mm). Larger sizes available on request.
