Available to purchase individually, although recommended to be bought as a pair. The left (280144.N) and right (280146.N) Stop and Clamping squares allow for multiple working heights with fine scaling along the side for repeatable accuracy.

With its unique design and larger size these squares provide more clamping options due to the increased number of boreholes.

The dimensions of the squares are 376mm long, 95mm wide and 800mm high. Due to its very large size, it can be used not only as a stop and square but as a large extension to the welding table. Perfect for precise, three-dimensional welding.

Made from GGG40 ductile cast iron and plasma nitrided, heavy-duty applications are no trouble for these highly durable pieces of tooling.

These clamping squares are available together as part of the Siegmund tool sets for the System 28
