SlotLock Anchoring Stake are great for landscaping, inflatables, tents, lawn, and ground blinds. SlotLock Stakes are fast to secure (no knots to tie), and make strap/rope tension easier to adjust. They are easy to use, even with gloves on. To use, feed the strap/rope through the barrel, pull the strap/rope up through the bottom cinch to secure, then lock the strap/rope in place with one of two methods. The first lock option is the quick lock, in which you run the strap/rope through both top cinches. The second lock option is the permanent lock, in which you run the strap/rope through one of the top cinches and then back through the barrel. If you need to re-adjust, simply unlock, pull tight, and re-slot the rope. Unlike knots that loosen as you tie them, with the SlotLock System, you can keep tension on the line as you lock it into the slot. SlotLock is constructed of Permalon, a premium, impact-grade, glass-filled, thermoplastic polymer that is virtually indestructible and impervious to the cold.
