The Rickenbacker 3x5 guitars (335, 365, etc.) shipped with an Accent vibrato. It used to be that swapping that out for a trapeze tailpiece meant drilling a new hole for the strap bolt because the standard trapeze bracket requires that hole to in a different place. That's not the optimal solution. This is: this bracket uses the original strap bolt hole to secure a trapeze compatible bracket. No muss, no fuss, no holes to drill.
NOTE: If you need a bracket for a 325, contact us first. There's some variation in the location of the strap bolt hole between the different variations, and the standard bracket may not fit every guitar.
