These 800- / 1200-mm-high stop and clamping squares feature a significantly reduced weight, and thanks to an aluminium-titanium alloy they are simultaneously extremely sturdy, ensuring comfortable, user-friendly handling at only 10.4 kg / 13.5 kg. The strained bar powerfully mortises against the work pieces, visualising strength in spite of the low weight of the tool. The lightness of the material allows for an optimisation of the hole pattern, with an additional oblong hole and further holes for flexible clamping in all directions. The squares are used for defined positioning and fixation of work pieces in welding and clamping applications.
