Product Specifications

Cable clamps often come in a variety of colors and sizes for different applications.  Important specifications to consider when searching for cable clamps include:

• The maximum diameter refers to the maximum diameter of the bundle of wires and cables
• The temperature range specifies the full-required range of ambient operating temperature. 
• Strain reliefs protect the lifeline of your electric products by absorbing the forces of push and pull that may be exerted on the flexible wires, cables, or tubing. 

Cable Clamp Standards

Common approvals for cable clamps include

• UL Listing Mark, and UL Recognized Component Mark (US and Canadian)-  The UL Listing Mark denotes that Underwriters Laboratories Inc. (UL) has found that samples of the product met UL's safety requirements. These requirements are primarily based on UL's published Standards for Safety.  UL Recognized Component Marks used only on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. Products intended for Canada carry the Recognized Component Mark "C."
• The CSA Mark may appear alone or with indicators. If it appears alone, it means that the product is certified for the Canadian market, to the applicable Canadian standards. If this Mark appears with the indicator "C and US" or "NRTL/C" it means that the product is certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards.
