For Split Panel Mounting Holes

  • Designed to be installed in a split panel mounting hole or dropped into a slot.
  • Can be used for one wire or bundles of wire (round or flat wire).
  • Securely anchors, insulates, and protects wire at panel entry points against forces of pull, push, or twist.
  • Part 1266 is assembly friendly and self-locks onto the wire. It may be preassembled offline for final assembly at a later time or remote location, for lower installed cost and faster assembly. It has a unique wire locking ratchet that allows for generous wire range from .250" (6,4 mm) to .600" (15,2 mm).
  • Part 1266 UL recognized for multiple cables/conductors.
