Once installed, you can easily adjust and calibrate the NoPlay miter bar from above on your sled! NoPlay Miter Bars are designed to be adjusted to fit your table saw, router table or band saw miter slot. Simply set it, test it and make any needed adjustments for the ideal fit. Each miter bar comes with a transparent stick-on template making installation a breeze! Can be mounted using the included wood screws that secure the bar through the bottom of your sled. Alternatively you can use the included machine screws to mount the bars through the top of your sled.
