The 69 and 912 Center-Rule Bench Squares will Make you Work Better

The 69 and 912 Center-Rule Bench Squares have a 1-1/2″ wide body and a 1″ wide tongue. The numbers represent the length of the tongue and body in inches. Both body and tongue, front and back, have zero point rulings on the inner and outer edges. There is also a Center-Rule Scale along the center of each leg—front and back. The Center-Rule makes these squares perfect when centerline datums are necessary. They also come in handy for remodel jobs, working with wanky stock or recycled wood. If maintaining natural curves and/or irregularities in the stock is desired—but also need to maintain a strict centerline datum—the Chappell Center-Rule Bench Squares at it best.

All Chappell Square Bench Squares are available in Imperial 1/16 Inch Ruling, The Chappell Decimal .05 Inch Ruling, and Metric Ruling. So, make sure to specify the ruling when you place your order.

Increase Your Layout Flexibility

When performing layout, the Chappell Bench Squares can work in tandem with our larger Framing Squares. You can nest them one to the other on the piece of work to extend locations and offsets from the primary datum point for end of tenons. This includes a secondary offset or layout marks. This is especially helpful in making perpendicular setbacks or parallel layout on rafters or any members requiring angle cuts.

Choose Your Ruling

Chappell Square Bench Squares are available in Imperial 1/16 Inch Ruling, Chappell Decimal .05 Inch Ruling, and Metric Ruling. Make sure to specify the ruling when you place your order.

The Chappell Decimal Inch Rulings are a favorite for Stair Builders and Machinists. Add a set of Chappell Bench Squares to the 1824 Master Framer and 1218 Traveler, and you’ll have a complete and seamless layout system. The decimal ruling is divided by the 1/4, 1/2 and 3/4 inch, and further into .05 inches. By combining fractional and decimal units seamlessly—there’s no need to convert back and forth from fractional to decimal units. The decimal units can be applied directly to the Decimal Inch Scale. For more about the Decimal Inch Ruling, check out the Chappell YouTube Channel.

No matter what the marking or layout situation—from large scale compound roof systems, to the most minute and intricate furniture and cabinetry layout—there is a Chappell Universal Square that’s right for you.
