The EZ123 Bottom Bracket: The Easy Choice.
The EZ123 Universal Bottom Bracket’s unique design allows for easy implementation and replacement of bottom rollers in tight installations, eliminating the need to take tension off the springs, clamp cables, or the bending or forcing of roller out of track. The bottom bracket is designed for both 50.8 mm (2”) and 76.2 mm (3”) rollers, which minimizes inventory costs. It can be used on all sectional door types, 38.1 mm (1-1/2”) up to 76.2 mm (3”) thick, including Aluminum Full View Doors. Made from heavy duty 12-gauge galvanized steel with aluminum roller holder, with a built-in pull cord/chain attachment, the EZ123 is designed to be the safest multi-purpose bottom bracket in the industry.
