Heavy-Duty High-Tension Hacksaw Frames, 12 in

Easy-to-use adjusting screw requiring minimal turns to tension the blade up to 28,000 p.s.i. (2,000 kgs/cm2). High-tension prevents twisting and binding of the blade when bearing down. Made of cast aluminum with an extra-thick tubular steel bar for added strength. Four permanently angled mounting pins allow for both straight and angle cutting. Closed grip.
