8715 Deluxe Stair Gauge Kit | Precision Stair Stringer Layout Tool

Laying out stair stringers with a set of cheap stair gauges can be challenging. The radiused edge of the stair stringer can cause you to guess where the tread and riser marks intersect.

This can throw off the gauges as you slide them along the stringer. Also the gauges small adjustment knobs make it easy to knock them out of position. Our Deluxe Stair Gauge solves all these problems, making your stair layouts quicker and more accurate!

Our Deluxe Stair Gauge tool features 1" long "legs", allowing you to make a short layout line at a right angle to the tread and riser line. In addition, these legs eliminate this guessing where the tread and riser marks intersect and makes it easy to index the square precisely to the next position.

Our 3/8" thick gauge body indexes against the edge of the stringer. This provides double the bearing surface of most gauges. and is not affected by the radiused edge of the stringer! Fits any steel or aluminum framing square (sold separately).

Easy to use large diameter knobs with brass screws hold the stair gauge firmly in position. Also includes a 24" long aluminum fence (optional use) to span voids and damaged edges. Plus it connects the two Deluxe Stair Gauges together providing extra insurance against getting knocked out of position.
