Abstract: A small, no-tools-required device, for example constructed of weather and UV resistant glass-filled nylon, that is inserted into the gaps between the deck boards of any conventionally constructed outdoor deck, then turned 90° like a key and released. Once tension is applied to the device through an attachment, for example using an elastic strap, a locking tab engages against the underside of the deck boards and the stabilizer tab at the opposite end of the device from the attachment prevents the device from twisting. The device can then be used to secure any items on the surface of the deck and prevent unexpected shifting or moving due to wind, weather, or any other unforeseen force. It is installed or removed in seconds and causes no damage to the deck itself.
