How to. I broke the band for my saw. I measure it's 56-7/8. That's why I'm ordering this. After waiting in the middle of my project through my fault for a new band, I got this and IT IS 60-1/2! What the hell. I'm angry at this moment. DO NOT BUY this product. Either Bosch doesn't know what he's doing, or it's the seller's fault. In addition, it is cheaply made. So light that it bursts under any pressure. This aggravates the situation. Take risks if you want, don't say I didn't warn you.
