GENERAL INFORMATION GENERAL INFORMATION The MQ MB25HD Rebar Bender is designed to be used as a portable on-site rebar bender, capable of bending in-place rebar to approved American Concrete Institute (ACI) radius. Labor time and injuries are greatly reduced from manually bending rebar. The MB25HD is capable of bends up to 180°. The MB25HD comes standard with 3 rollers and 5 collars which can be used in different combinations to match the diameter of the rebar to be bent.
