Worried about forgetting to put the plug in? Everyone is... , but NOT anymore. Here is Plug-Mider, the boat plug holder, reminder, installer and remover tool, for all 1/2" NPT drain plugs. If added to your boat's key chain, you will never, ever forget to put your boat's drain plug again. Why? because you will have it in your hands all the time while you are preparing your boat for the trip. Oh..., don't have a heavy metal, and probably rusted tool? Don't worry; this is also your installer/remover tool. This is so practical... It should be added to everyone's boat key chain. It is only 5 inches long, but be sure you can put enough torque to tighten your plug very securely. Is made out of PA-66, nylon plastic and it has 30% glass fiber added also; so, you can count on it... will not break. That's why we can offer life-time warranty.
