Drain Plug Modification
Category: Boat miscellaneous, boat hardware, March18
Problem: Drain plugs that are used in boat drains and other locations that twist to expand the rubber and tighten, creating the seal, sometimes are difficult to turn without turning the whole plug, making it difficult to tighten and seal. One has to remove the plug, tighten with both hands until it is approximately the right size, and then reinsert it in the opening. This can be particularly vexing if the opening is in a hard to reach spot.
Action: To keep the plug part from turning I added a protruding piece (wing or leg) that can easily be grabbed and held or turned against something, stopping the plug from turning and allowing the twisting motion of the handle to proceed to tighten and seal. There is usually not an issue when the plug is loosened, because it is already held in place.
Result: The plug can be inserted and easily tightened in one operation. The protruding arm even permits this to be done with one hand with the thumb and first and third fingers turning the handle, and the second finger holding the arm in place.
Additional Thoughts: The arm could be made to swing out or be left in depending on the need. The arm also permits the plug to be turned after it has been loosened in case it has become stuck to the inside surface of the hole. Otherwise after it is completely loose, the current plug design permits the handle just to spin within the plug.
