Both of the round handles for my 2012 Keystone fifth wheel broke. The finger that extends to engage the push-down latch broke off of one of them, rendering the handle non-functional. This part replaces the outside/back piece, snapping into the four prongs that protrude from the inside/front piece.

I chose to put glue on the prongs to avoid separation, as happens with the stock piece as well.
