Create a made-to-measure base for your ULTRA MFT Frame using our online 4040 Base Builder. Enter your required finished length, width and overall working height, then choose between lockable castors or adjustable feet. Each base is manufactured from strong 4040 aluminium extrusion and supplied as a flat-pack kit with the required braces, mounting brackets, connectors and fixings. The system automatically calculates the correct upright and brace lengths to suit your selected frame dimensions and finished working height. Choose lockable castors for a mobile workstation or adjustable feet for a stable, level working surface. The completed base is designed to fit beneath the corresponding ULTRA MFT frame and 18 mm MFT top. Before development, the only essential measurements still to verify are the precise fitted height of the castors and the minimum fitted height of the adjustable feet. We will also need to set the permitted minimum and maximum finished table height.
