Cable tie wraps are made in the USA and constructed of nylon. Advanced pawl-design produces superior locking power. Low profile head enhances appearance and "snag" resistance. Elimination of ejector pin marks along the strap promotes smoother pull-through. Rounded edges reduce insertion force and surface abrasion. Ridges provide convenient finger grips for firmer pull-through. Gusset-style reinforcement adds strength to the neck. UL recognized. Choose from 6, 11 or 14" length.
