My 23B uses a small black T-handle that fits on a square pin that is recessed in the bunk end latches (2). So far mine are holding up but I think there was some lettering on them that indicated they were made in Germany. I think there was a thread on the hybrid explorer forum where someone was looking for a replacement.
