Zip-Clips are suitable for use with single or multi-tiered trapeze systems and in applications supporting such items as cable trays, baskets, water and gas pipes and chilled beams. The Zip-Clip cable lock combined with cable and unistrut is an efficient method of constructing a support structure. The Zip-Clip fits inside unistrut and has a spring loaded pawl which allows entry and passage of cable through the cable lock. Once engaged by the pawl, the cable is gripped with increasing pressure as the suspended load is increased. To ease adjustment, each Zip-Clip cable lock has an integrated release pin to disengage the gripping pawl. Zip-Clips are sold in sets with looped cable. To insure the integrity of the suspension system use only Rize cable supplied in the set.
