Using this grade chair is easy. First, choose the right height combination based on your grading conditions. Then, place the chair on the soil where you need to secure the rebar. Next, use the 'Snap - in top' to lock the rebar into the chair firmly. When handling, be careful not to drop the chair from a high place as it may damage the polymer composite material. For maintenance, keep it in a dry place to prevent any moisture - related damage. If you notice any cracks or significant wear, it's a good idea to replace the chair to ensure continued stability and performance.
