The internally toothed REZ band has a unique, patented head that allows for easy and quick use. Fastening and tightening are done in the standard way. The quick-release mechanism allows for fast loosening of the band with one hand, even when wearing gloves. Detachable bands are perfect for use in temporary installations or in situations where wires are added or removed. They can also be used in many other areas, such as the packaging industry to close bags when access to the bag's contents is required or when re-closing is necessary.
