Automatically goes to any position from the blade and can push material that weighs up to 90lbs. Accurate to .004" and is bang on when set up right. Reduces cutting time by at least 50% and makes you a ton of money. Only reason I am selling is that we are getting a bigger, more automated machine and need the space to put it. 22' Overall length allows cuts on stock up to 20' long. Can be used on metal cutoff saws, bandsaws, miter saws, or upcut saws.
