Pivot lock
Thanks for posting. I am confident we can help replace this pivot shoe, but we carry many kinds with a very similar appearance, as you can see here. The best thing to do is to tell us the exact width and thickness of the shoe. Give us those dimensions, and we should be able to narrow down your options. Many thanks.
Also the lock seems to have metal teeth.
Thanks! That's a huge help.
My top recommendation is the 15-047. The design may look very different at first glance, but it should still work in the same capacity. It's the same size at 1-1/4" wide x 5/8 thick, the cam appears to be the same style, and while ours doesn't have the same metal "hooks" at the top that yours does it's still compatible with the same balance hardware.
As long as the dimensions match up, I feel confident that this pivot shoe will replace your original despite the stylistic differences.
Anytime! Please don't hesitate to reach out if we can be of any further assistance.
