Patented PlugKeyper drain plug reminder with a built in wrench to install and remove your drain plug. Use the PlugKeyper to attach your drain plug to your keychain or take it a step further and use it to lock your ignition key into the device using the boat drain plug! The PlugKeyper is designed to lock your ignition key into the device by screwing the drain plug down on top of it. This will prevent using the boat while the plug is out. The plug, key and float are NOT included. This item only contains the plastic PlugKeyper and a small keychain. This item is simply a reminder device that the drain plug is not currently installed in the boat.
