Our standard design, used in diagnostic applications, is suitable for use within walls where their overall density and thickness provides the necessary shielding. If lead is the primary shielding material this design assumes that it is installed on the inside wall of the x-ray room. To calculate the structural opening using our standard hardwood doorframe (45mm thick), add 100mm to the width and 50mm to the height of the proposed door size. Unless otherwise requested, doors are constructed to open into the X-ray room. Handing Arrangements When placing an order, please also confirm handing arrangements. Single Doorsets With door opening towards you are the hinges on the left or right hand side? Double Doorsets With doors opening towards you are the hinges supporting the leading leaf on the left or right hand side?
