I know it's only a silly little winch handle.... but there are very good reasons why they (not ours) get stuck in a winch. I literally measured 100's of winches of differing makes and models before settling on the measurements for our Dax OneTouch. The result is I have never had anyone say a Dax handle will not fit (and lock) into a winch.

In general, both Lewmar and Harken are fairly standard - its the older Barrients and Barlows that present the real challenge.

To be told 'oh, you're using it in a Harken winch' is unbelievable. There's just no excuse for that sort of thing. Lewmar went there own way in building their version of my design. They ignored my measurements in the process. I had no control over that. Very sad.
