Will item Q76-9059 Footplate quick release pin work for the Inverness Pronto M51 model footplate?
The shaft on this push button quick release pin measures 1/4" in width and 1-1/2" in length. Unfortunately we no longer have the footplate from the M51 to test it on since it is discontinued. With that being said, as long as the measurements provided line up with what you have then it will probably work. If you decide to order and it doesn't work you can always return it within 60 days in new/unused/undamaged condition for a refund.
