The REZ300 is a Cable Tie made of polyamide 6.6 (PA66). It features inside serrated with one-hand release mechanism. The unique, patented head design enables quick and simple use. The tie can be inserted in the normal way and pulled tight or the tail can be twisted into the open part of the head and locked into place. The quick-release mechanism can be released by one hand - even when the tie is under tension - by simply pinching the ears. This releasable and reusable tie is ideal for temporary installations or the addition and/or removal of cables. Suitable for a multitude of uses, such as the packaging industry as a bag closure where access to part of the bag contents may be needed but the bag needs to be re-sealed.
