Use only copper sleeves for maximum safety in securing applications

Compression sleeves made of copper provide maximum reliability and long life. It is recommended that only copper sleeves that are manufactured to the US Military Specification (Mil-Spec) MS51844 be used in cable connections where reliability and general safety are a primary concern.


The Locoloc® brand copper sleeves sold by Loos & Co. Inc., Cableware Division are manufactured to the US Military Detail Specification MS51844. The latest revision of this specification is MS51844D dated 19 April 2007. A copy of MS51844D can be found here..
