Słowik angle square with cross bar 100 x 50 cm model 50101, construction measuring tool

Słowik angle square with cross bar 100 x 50 cm model 50101 is a construction measuring tool designed to check and mark right angles on large workpieces. The 100 x 50 cm frame and rigid cross bar offer a stable reference for squaring panels, rafters, wall corners and other structural elements on-site. The tool is suitable for use in framing, masonry and carpentry where precise 90° alignment and repeatable layout are required.

Advantages

The angle square combines a large measuring frame with a solid cross bar that reduces flex during marking and alignment. Its dimensions provide extended reach for bigger panels and assemblies while remaining compact enough for handling on site. The simple open-frame design allows clear sight lines to the work surface for accurate transfer of lines. The tool is durable and intended for repeated use in construction environments.

Suitable for

• Squaring timber frames and roof rafters
• Checking and marking wall corners and masonry layouts
• Aligning large panels, sheets and formwork
• On-site joinery and general building layout

Key specifications

• Overall frame dimensions: 100 x 50 cm for large-area marking
• Rigid cross bar for stable reference and reduced deflection
• Open-frame construction for unobstructed visibility of the work surface
• Intended for manual marking and visual alignment at 90°
• Suitable for use in framing, masonry and carpentry applications

How to use

Place the angle square so that its two legs contact the surfaces that form the intended right angle. Press the cross bar gently against the workpiece to ensure a stable reference. Use a pencil or marking tool along the frame edge to transfer the 90° line. For repeated markings, maintain consistent pressure and sight down the open frame to confirm alignment before scribing. For checking already assembled elements, align the tool against the reference face and observe any gap or offset to determine adjustment needs.

Usage recommendations

Store the tool in a dry place and protect it from heavy impacts to keep the cross bar straight. Clean debris from the contact edges before marking to ensure accurate lines. For best results on irregular surfaces, press the cross bar firmly and verify alignment visually at multiple points along the frame.
