ASP Tri-Fold pull rings are very convenient and attach directly to the end of any ASP restraint. The ring provides a firm grip for quick application of the restraints. The pull ring will also allow for quick and easy removal of restraints from a duty case. The ring snaps on to each restraint and can be reused over and over again. (1 pull ring is automatically included for every 6 tri-fold restraints you purchase). ASP Model 56215.
