Garage Door Track Clamp-On Roller Stop
A bolt-on stop block for a garage door roller track. It clamps onto the track flange with an M5 x 25 bolt and a captured M5 nut. The 10 mm jaw gap fits flanges and rolled lips up to about 9 mm thick. The 30 x 30 mm hollow block sits in the roller's path, so you can lock a door that has no lock or hold a roller in place while you work on the hardware. Overall size is 30 x 58 x 22 mm.
