The CRA/CRO Couplers connect components in the horizontal lifelines for a complete system. We have 6 different devices to choose from based on your needs. Couplers are all made from heavy gauge 304 or 316 stainless steel and are supplied with stainless steel bolts to attach the components together. Designed primarily for SAS engineered HLL systems to link turnbuckles, energy absorbers and 3/8 in wire rope eye thimble terminations. Designed specifically for use with SAS commercial anchors, these components can be used with other mfg. equipment when engineered by a qualified person.
