Angle Square with Base Helios Preisser 50 x 28 cm model 0374418

Helios Preisser angle square with base model 0374418, size 50 x 28 cm, is a metal measuring and marking tool intended for workshop and metalworking tasks. The tool combines a right-angle blade and a supporting foot to provide stable layout, accurate squaring and scribing on sheet metal, plates and assembled parts. The rigid construction and flat reference surfaces allow repeated checks of 90° edges and reliable transfer of layout lines during fabrication and assembly operations.

Advantages

The angle square features a robust metal construction and a wide base that improves stability when placed against workpieces. Its long blade and precise right-angled junction enable accurate marking and squaring over longer runs. The integrated supporting foot keeps the blade perpendicular to the reference surface, reducing play and ensuring consistent contact for repeatable measurements. The simple, compact design is suited to workshop conditions and allows quick positioning for layout and inspection tasks.

Suitable for

• Checking and marking 90° edges on sheet metal and plates
• Transferring and extending layout lines across parts
• Fixture setup and alignment in fabrication and assembly
• Scribing and guiding saw or cutting lines for metalworking

Key specifications

• Material: metal construction for durability and rigidity
• Blade length: 50 cm
• Base depth: 28 cm for improved stability
• Angle: precise 90° right-angle junction between blade and base
• Reference surfaces: flat blade and base for reliable contact

How to use

Place the base flush against the reference face of the workpiece so the angle square sits steadily. Align the blade along the surface where the 90° line or mark is required, then use a scribe, pencil or marker to transfer the line along the blade edge. For checking perpendicularity, hold the base against one face and observe contact along the blade; any gap indicates deviation. Use the base to steady the tool while setting up fixtures or guiding a cut, keeping hands clear of cutting paths and rechecking alignment after repositioning.

Usage recommendations

Maintain clean, burr-free reference surfaces on both the blade and base for accurate contact. Store the angle square in a dry place to avoid corrosion and inspect periodically for bends or wear that could affect squareness. When marking, use a sharp scribe for best precision and reverify critical measurements before final assembly or cutting.
