The “Rock Solid” Kreg® Production stop sets the distance from the end of the board and the saw blade for amazing cutting accuracy and cutting repeatability. The Kreg® Production Stop is perfect for repetitive, high-production applications. A unique dovetail design drops onto the top of the fence, which means there is no need to disassemble to move the stop to the other side of the blade. The dual, adjustable precision lens’ (cursors) reads from either side of the sawblade. The precision lens' are marked with a red hair line for easy visibility when aligning.
