MECHANICAL POWER LEAF BRAKES:
Standard, or Box & Pan, in regular, medium and heavy duty capacities. Every power leaf brake we sell includes power clamping and motorized top leafs for maximum productivity.
Everything is solidly built to last for many years, from the welded steel plate frames with box type support for maximum strength to the powerful gear head motors with built-in magnetic brakes.
These power leaf brakes offer the kind of staying power and efficiency that includes radius bending abilities usually associated with roll forming equipment or stamping presses.
Our Box and Pan versions are just as rugged and stable as our standard models. The sectional, adjustable, finger assemblies even let you bend five sided boxes, pans, and other shapes such as tubes, with ease.
