Running cables through metal studs can be a nightmare because pulling the cables too fast can cause abrasion on cables or wires removing protective insulation layer which prevents interference between other application wires.
GREENLEE GL-712A100 Bushings for Metal Studs are constructed of PVC (Poly Vinyl Chloride) which is fire and water resistant. The PVC bushings have a smooth finish all around allowing for quick and easy installation of all your cables without inflicting any damage. Not only does the triple lock mechanism keep these bushings locked to 12 or 24 gauge metal studs but also prevents damage or abrasion from happening when bundling up to 10 electrical cables at once. These insulation rings are UL listed, CSA Certified and come with a 1 year warranty.
