RS 18 & RS 30


In the RS 18 and RS 30, SOLA is expanding its range of squares with two new rafter squares with edge lengths of 18 cm and 30 cm. Both rafter squares are in the shape of an isosceles right-angled triangle with a T-edge on one leg and they combine the features of a ruler, try square, miter square, angle meter, and a rafter measurer. In addition, they can be used as a scribing tool or a saw guide, thanks to their durable edge. Made from aluminum, the rafter squares are lightweight, yet robust and durable.


Multi-talent for Marking

The SOLA rafter squares are true multifunction tools thanks to the number of recesses and metric scales on both sides in both mm and cm, making them ideal for marking lines and angles. The offset scale beneath the T-edge means lines can be marked perpendicular to the T-edge. If you are looking to mark or scribe parallel lines with a pencil, use the scribing notches at 0.5 cm intervals.


0–90° Angle Measurer

If the rafter square is placed with the T-edge on the rafter or workpiece, you can quickly and easily mark or check a 45° or 90° angle. Any angle between 0° and 90° can be measured using the degree scale on the hypotenuse of the rafter square. To do this, simply rotate the rafter square around the pivot point to the desired angle on the degree scale.


Rapid Marking of Miter Cuts

The different scales and recesses of rafter squares are primarily designed for use with wood – be this during carpentry, joinery or woodwork. Rafter squares are a key part of the carpenter’s toolbox during roof construction and for rafters. As well as the degree scale, they also have a recess with two special scales for marking common, hip, and valley rafters. In addition, the SOLA rafter squares have a 90° marking aid for rafter seat cuts.


Robust and Durable

SOLA rafter squares are made from lightweight aluminum and score highly thanks to their robustness and durability. The scales on both sides are lasered, dazzle-proof, and have enhanced contrast, which means you can quickly and comfortably read off measurement results.


Alongside the RS 18 and RS 30 metric rafter squares, SOLA also offers 7″ (RSI 7) and 12″ (RSI 12) imperial rafter squares.
