Their fully insulated plastic saddles prevent cable damage and provide the safest installation for electrical wiring. They are individually injection molded from the best plastic available for this application. Their superior impact strength is retained even at low temperatures. The nails used in our straps are zinc plated, and a new yellow chromate provides improved corrosion protection. Their small diameter allows them to be driven easily without splitting the wood. The nails are held in driving position to speed the installation of cable, even in vertical or overhead positions. They are premium quality straps sold at reasonable prices. We are a family-owned company that has been able to develop highly efficient manufacturing techniques during the many years of producing HANDY STRAPS. Black colored straps with a UV stabilizer are available to resist the effects of sunlight.
