The precision engineered design of the STEREN GRIP-Clips makes installations easy and clean. No experience required. Designed and Manufactured from an extremely durable polyethylene, which is the same material of cable jackets, the STEREN Grip-Clip wrap around the cable without applying pressure on the cable. The adjustable “teeth” enables the STEREN Grip Clip to expand when needed, therefore, allowing for a superior fit. This also allows for an expansion of the Diameter allowing other wires to fit. The pre-inserted Screws ensure that there is no accidental damage from tools such as hammers during installation. These pre-inserted screws make the installation quicker and hassle free. The unsurpassable and exceptional design of the STEREN GRIP-Clips maintains the integrity and consistency of the signal by avoiding stress on both the cable and the clip itself, making the life of the clip is unrivaled.
