Angle square with base Helios Preisser 30 x 18 cm model 0374414

Helios Preisser angle square with base model 0374414 measures 30 x 18 cm and provides a fixed 90° reference for carpentry and metalworking tasks. The tool combines a right-angled steel blade with an attached base that ensures stable placement on workpieces and benches. It is intended for layout, marking and checking of right angles on wood and metal, offering a rigid reference for repeated measurements and transfers.

Advantages

The angle square's welded construction and steel material deliver dimensional stability and resistance to bending during routine workshop and on-site use. The attached base allows the square to sit flush on flat surfaces for more accurate marking and reduces rocking compared with a blade-only square. Its 30 x 18 cm dimensions make it compact enough for handheld use while providing sufficient length to align edges and faces on small and medium workpieces.

Suitable for

• Layout and marking of right angles on wooden boards and metal plates
• Checking squareness of joints, frames and assembled parts
• Transfer of perpendicular lines from one piece to another
• Use on workbench surfaces and in mobile on-site setups

Key specifications

• Overall blade length: 30 cm
• Base depth: 18 cm
• Material: steel construction for rigidity
• Fixed 90° angle between blade and base
• Welded/joined base for stable seating

How to use

Place the base of the angle square flat against the workpiece edge or on the bench so the blade extends along the surface where you need a right angle. Use the blade as a straight reference to scribe, mark or clamp along its length. For checking squareness, align one face with the base and inspect contact along the blade for gaps; rotate the square and repeat to confirm accuracy. When transferring lines, hold the base firmly to avoid movement while marking along the blade.

Usage recommendations

Keep contact surfaces clean and free from debris to maintain accurate seating. Store the angle square in a dry place and avoid heavy impacts that could deform the blade or base. For precision work, verify squareness against a known reference before critical marking or assembly.
