Corner Square with Base Helios Preisser 25 x 16 cm model 0374412

The Helios Preisser Corner Square with Base 25 x 16 cm model 0374412 is a precision metal measuring and marking tool designed for reliable 90° layout and alignment tasks. It combines a right-angle working edge with an attached supporting foot to provide stable contact on workpieces, making it suitable for both metalworking and carpentry. The tool's compact size and rigid construction allow for accurate checking of corners, transfer of lines, and consistent positioning during fabrication and assembly operations.

Advantages

The corner square offers a rigid, wear-resistant metal edge for repeatable 90° checks and marking. The integrated base stabilizes the tool on flat and slightly irregular surfaces, reducing movement while scribing or clamping. Its compact footprint and low profile make it easy to position in confined spaces and along edges, while the clear right-angle reference speeds up layout and inspection tasks. Overall, the design supports improved accuracy and workflow efficiency in workshop and on-site environments.

Suitable for

• Checking and marking 90° angles on metal and wood
• Layout work for fabrication, welding, and joinery
• Positioning and aligning parts during assembly
• Inspection of corners, edges and squareness in workshops and construction sites

Key specifications

• Material: durable metal construction for dimensional stability and wear resistance
• Overall dimensions: 25 cm by 16 cm working face for compact but practical coverage
• Fixed right-angle edge for marking and measuring 90°
• Attached supporting base to provide stable contact and prevent wobble during use
• Low-profile design to fit into confined spaces and along edges

How to use

Place the corner square so the supporting base rests firmly against the workpiece and the right-angle edge aligns with the surface or edge to be checked. Hold the tool steady with light pressure on the base while scribing or marking along the edge with a pencil, scriber or marker. For inspection, press the base flat against the surface and verify that the workpiece aligns flush with both faces of the square. When clamping or welding, use the square to position parts before securing to ensure consistent 90° alignment.

Usage recommendations

Store the corner square in a dry place and avoid dropping or striking the precision edges. Clean metal shavings and debris from the base and edge after use to maintain accuracy. For best results when marking, use a sharp scribe or fine pencil and verify alignment periodically during multi-step assemblies.
