The BT-1 can be used to bend all such I-beams simply by placing the track on the floor and positioning the bender at the location where the curve is desired. Leverage is exerted at the handle of the bender to form the curve. 48” long x 15” wide x 9” high. For use with Models 1300, 1400 & 4200 tracks.
