Each cover comes standard with four tie-downs equipped with locking child resistant safety latches. To assure the integrity and prevent the straps from ripping out (perhaps from high winds), the straps are sewn into the cover in four places, including the skirt. This makes them virtually tear-proof.
Besides aiding in keeping out unwanted visitors, the tie-downs, when properly used help to prevent strong winds from blowing off the cover. There is also the option of additional tie-downs.
The "locking latches" are molded after the quick release buckles found on sports equipment and have been specifically designed for spas! Each NMF Fastener may be locked down individually. They are quickly installed with three stainless steel screws (provided).
