When we heard some of our distributors found it a hassle having to use M12 bolts solely for the baseplates’ conical couplers while they mostly work with M10 bolts we wanted to come up with a solution. And yes, of course we did! Never swop between M10 and M12 bolts ever again, with our small addition to our assortment: the Reduction ring. Simply place the ring between the M10 bolt and the baseplate to reduce the space you would normally have because you are using a smaller bolt.
