R19 ROBOTS are required to use BUMPERS to protect all outside corners of the FRAME PERIMETER. For adequate protection, at least 8 in. of BUMPER must be placed on each side of each outside corner...

that's right but your drawings above put the bumpers over the threads. The plywood backing have to start beyond the threads
