Helios Preisser Square with Base MKSC 40×20 cm model 0372108, steel measuring angle

Helios Preisser Square with Base MKSC 40×20 cm model 0372108 is a steel measuring angle engineered for accurate 90° layout and inspection tasks. The tool combines a stable base with precise right-angle edges to support squareness checks, marking and transfer measurements in workshop environments. Its steel construction and flat faces make it suitable for repeated use in carpentry, metalworking and assembly operations where reliable right-angle references are required.

Advantages

The measuring angle provides a rigid base that ensures stable positioning on flat surfaces and workpieces. Precisely machined edges deliver accurate 90° alignment for checking squareness and marking out. The steel body offers wear resistance and long-term dimensional stability under typical workshop conditions. Compact dimensions allow easy handling and positioning while the flat reference surfaces facilitate consistent measurements and transfers.

Suitable for

• Checking and marking 90° corners in carpentry and joinery
• Squareness inspection and transfer measurements in metalworking
• Assembly and fixture alignment where a stable right-angle reference is needed
• Layout work on flat plates, frames and panels

Key specifications

• Material: steel construction for durability and dimensional stability
• Overall measuring faces: 40 × 20 cm for extended reach and support
• Angle accuracy: machined right-angle edges suitable for precision layout and inspection
• Base: rigid flat base for stable placement on workpieces and surfaces
• Finish: machined faces to provide clear reference edges for marking and checking

How to use

Place the base of the square flat against the reference surface or workpiece so that the machined edges are flush with the faces to be checked. For squareness checks, align one face against one edge of the square and observe or mark along the perpendicular edge to verify or transfer the 90° line. Use the flat base to stabilize the tool while scribing, measuring or clamping. For repeated checks, ensure the reference surface is clean and free of chips or debris before positioning the square.

Usage recommendations

Store the steel square in a dry, protected location when not in use to minimise corrosion and preserve edge accuracy. Regularly check the machined faces for nicks or wear and clean the reference surfaces before critical layout tasks. When greater precision is required, use alongside calibrated measuring instruments or surface plates for verification.
