This mitre fence has a solid steel bar 19mm x 9.5mm (3/4" x 3/8") and 320mm long. It will fit onto any machine or router table with a similar size groove. Installation is simple and you can make the bar a perfect fit in your mitre slot. The bar has a removable locking washer at one end for T-slot grooves. If you have a plain slot, just unscrew the washer. Along the side of the bar, three adjustable grub screws, allow you to remove any play between the bar and groove for smooth, accurate operation. Once set up in your machineβs slot, it will allow you to cut accurate mitres every time. This quadrant is robust 5mm steel plate featuring positive stops at 0Β°, 22.5Β°, 30Β°, 45Β°, 60Β°, 67.5Β° and 90Β°. A spring-loaded plunger locks into the indents for rapid adjustment to common angles. The pointer and degree scale allows you to set the quadrant to any other angle between 0Β° and 90Β° left and right as required.-bg
