I'm looking to purchase three units of a sturdy stand designed to support a granite surface plate. The dimensions required are 1400 mm in length and 1050 mm in width, with an overall height of 800 mm when combined with the granite piece. Please provide your best pricing and availability for these units. It would be great to know about any additional features or options you might have for this type of stand. Looking forward to your prompt response!
