Notes from the maker
- Capacities are for mild steel. The maker's page does not mention aluminum: for what a brake does in aircraft alloys, see the bending guides.
- HBU48-16 comes with an apron stop rod, extension handles and a counterweight. Radius fingers are an optional add-on, and its removable apron angle and insert allow 1/4 in reverse bends in lighter materials.
- The lighter 22 gauge models are easier to transport to remote job sites.
