The KEY-BAK #6C Retractable Reel is Made in USA with globally sourced materials and engineered for a lifetime of use. Built with the best quality stainless steel spring, this tough, versatile retractor is smaller and more discreet than our Original Series for greater flexibility. The case is made of strong polycarbonate and with 6 ounces of retraction force, the reel will hold anything equal in weight to 10 large keys. The #6C attaches with a zinc alloy carabiner to any belt loop or strap. Originally invented in 1948, KEY-BAK reels have become an invaluable tool for professionals who rely on secure and convenient access to their keys. KEY-BAK reels also work for small hand tools, gauges, flashlights, identification and outdoor gear. We stand behind every product we manufacture with a Lifetime Service Policy.
