The ratchet wrench was invented so people wouldn't have to remove the wrench from the bolt for each turn. For decades, this innovation has been put to good use on drums. The ratchet lug wrench is perfect for hurry-up-and-tune situations. Imagine this familiar scenario: one of the kids marching tenors busts the 10" head on the last note of the lot, just before you start walking to the field. You need to replace/tune a new head fast - nothing works better than a ratchet lug wrench. This tool is heavy duty to stand up to the wear and tear of everyday use, and includes a clockwise/counter-clockwise switch.
