If you have purchased your Base Cabinet from us, and you have decided to buy your Bi-Fold door separately, you are in the right place. You just need to select your desired height, width, material and colour. We will handle the placement of the hinges based on our standards. Therefore, the height of the top and bottom hinges is 100mm. The rest of the hinges, if any, will be distributed equally in between. Please note that the Soft Close hinges are included complimentary upon finalising your order.
