Renovating an old wooden staircase is one of the most ambitious DIY projects out there. However, the wolfcraft folding gauge dramatically simplifies the process of measuring the steps, even in old spiral staircases: it helps you master unequal angles, curves and the consideration of expansion joints and material allowances with confidence.

This stair folding ruler combines the advantages of a stair spider tool with those of a conventional template or angular bevel gauge. Integrated expansion joint wedges and adaptors for the material allowance (e.g. for the steps) complete the set.

High-quality screws with wing nuts hold the template steadily in position so that you can transfer the dimension to the work piece confidently and without errors.
