Renovating an old wooden staircase is one of the most ambitious DIY projects out there. However, the stair gauge dramatically simplifies the process of measuring the steps, even in old spiral staircases: it helps you to master unequal angles and curves as well as take account of expansion joints and material allowances with ease. The stair gauge combines the advantages of a stair spider with those of a conventional template or angular bevel gauge. Integrated expansion joint wedges and adapters for the material allowance (e.g. for the steps) complete the set. High-quality bolts with wing nuts hold the template securely in position so that you can transfer the dimension to the workpiece confidently and without errors. Set Includes: 13 galvanised steel rails, round 2 galvanised steel rails, pointed 15 screws with wing nuts and washers 1 flexible chain element 6 spacing guides for expansion joints 2 protrusion gauges
