Never worry about the safety of your spa again with Steel Core Spa Safety Straps. Whether you’re going on vacation or barbecuing with the kids, these straps will keep your hot tub inaccessible and securely locked. Designed for home spas, each 13 foot strap is made with a patented sewn steel covered webbing. This webbing is a blend of steel and cut resistant fibers to form a webbing that is harder to cut than steel cables and virtually impossible to remove once locked.
