Miter GageT by Incra sets a new standard. Unique saw-tooth positive angle stops allow for extremely accurate adjustment in increments of 1 degree, (not just 22.5, 30, and 45 degrees like most gages). Of course, sometimes you need to fine-tune the angle to get the hairline glue joint that marks fine craftsmanship. The Incra folks have thoughtfully provided an adjusting slot that allows for up to 1/2 degree of positive or negative tweaking at every index stop. In addition, there is a positive stop at 22.5 degrees to make it easy to achieve perfect results with the ever popular octagonal picture frame or box. All of that accuracy would be meaningless if the miter bar wiggled around in the miter slot so you can be sure that the Incra GlideLockT Miter Bar fits like a glove. Special expansion disks on the steel bar allow you to custom fit it to your table!
