The maximum flange length for 4-sided box bends is 3.50″ if no hardware will be installed. If hardware will be installed, the maximum flange length is 3.00″. Please keep in mind that the base of any 4-sided box will need to meet our u-channel requirements (the base should be 2x as wide as the flange length).
