A hand crimped copper button stop will provide a holding strength approximately 1/3 that of rated cable strength. Machine swaged copper button stops provide up to 50% of the cable’s break strength. Greater holding strength is one reason why Lexco prefers to prefabricate our customers’ cable assemblies. A pull test is always recommended to verify a button stop’s holding strength.
Copper button stops are available for cable diameters from 1/16” to 5/16”. Standard button stops feature a plain finish. Zinc plated copper button stops are available upon request.
Our copper button stops can be provided with certificates of RoHS conformance upon request.
Note: The holding strength of a copper button stop is affected by the construction of the cable onto which it is installed. A button stop installed on a 1x19 cable will yield a different holding strength than an identical button stop installed on a 7x7 cable, for example.
