Angle Ruler Słowik K00 100×100 cm — model 50100-100, steel corner square

Słowik K00 angle ruler 100×100 cm (model 50100-100) is a large steel corner square designed for precise layout and measurement of right angles in construction, carpentry and joinery. With two perpendicular 100 cm edges, the tool provides an extended reference surface for marking, checking squareness and transferring 90° lines on boards, panels, frames and other building elements. The robust steel construction gives dimensional stability and a straight edge suitable for site work and workshop use.

Advantages

The steel corner square delivers a long, accurate reference edge that reduces repeated measuring and speeds up layout tasks. Its rigid construction maintains perpendicular alignment under regular use, while the wide arms allow clear, continuous marking across large workpieces. The simple, open-frame design makes it easy to position the square against edges and corners, and the steel material resists warping compared with thin or composite alternatives.

Suitable for (tasks / use cases)

• Checking and marking 90° angles on boards, panels and sheet materials
• Transferring right angles during frame assembly and carpentry
• Layout and squaring of doors, window frames and furniture components
• Site and workshop measurement where a long, straight reference edge is needed

Key specifications

• Material: steel construction for rigidity and durability
• Arm length: 100 × 100 cm perpendicular edges for long reference lines
• Shape: right-angle corner square designed for marking and checking 90°
• Finish: smooth straight edges suitable for pencil or scribe marking
• Application: manual measurement and layout for construction and woodworking

How to use

Place the inner corner of the angle ruler against the corner or edge of the workpiece so both arms sit flush along the surfaces to be squared. Hold the tool firmly to prevent movement and use a pencil, scribe or marking knife along the outer edge to draw the 90° line. For checking squareness, align one arm with a reference edge and verify the second arm runs true along the adjacent surface; if gaps or misalignment appear, adjust the workpiece or framing until the arms contact evenly. When transferring angles across longer panels, slide the ruler along the edge and redraw as necessary to maintain continuity.

Usage recommendations

Store the steel angle ruler flat or hung to avoid bending; clean the edges after use to remove debris that could affect accuracy. Use gentle clamping when marking to prevent the tool from shifting, and inspect the straight edges periodically for nicks or wear if precise layout is required.
