The ultra-high With URHR grommets, repair or rework expansion ratio material conveniently fills is a snapsimply heat the grommet until the space between the clamp type soft and slide a NON-METALLIC probe connector accessory and the cable. through the center of the wire bundle When clamped into position, URHR enlarging the grommet I.D. Once cooled, grommet provides strain relief that is more the grommet will remain open allowing consistent and convenient than many wires to be added, removed or reworked. conventional practicesfor example, The system can then be checked, the taping, grommet, or tape/ grommet grommet reheated (shrinking it down combination.
