The Sentinel trim block lock is used on the Slingshot above the bar de power systems from 2016 to the present day to lock the line in place witihn the trim block. It's a plastic/nylon rectangle with a stainless steel allen screw in it that fits in the block as can be seen in one of the photos. Reasonably easy to fit.
The pack contains one complete Sentinel plastic trim block lock with stainless steel allen screw.
