The Holding Frames can be joined together to form a bank of any dimension. The usual method is bolting. They can however be tack welded to form a solid construction.
It is essential that bracing or support strips are used if the filter bank is greater than three filters high by four filters wide. The recommended format is to place a VERTICAL steel strip 50 mm x 2.0 mm between the frames as they are bolted together. This is required every two frames wide. See SHF installation instruction sheet.
