Frame Dimensions

The frame dimensions are shown in the sketch below:

• There are 3 crossbars in the frame, these are fixed, i.e. cannot be moved
• This results in 4 rows per frame, which can be filled with display sheets
• The rails and the profile frame each have a retaining groove of approx. 9 mm depth at the top and bottom, where the protective covers are inserted
• The sheets are additionally stabilized by a transverse plastic string
• This retaining string is 19 cm above the moulding
