Surplus room in each frame is filled out with solid insert blocks. Called spares, they bear the designation A/0. Blocks are referred to by their width (A), followed by the designation /0 (indicating solid). Thus a block with a width and height of 15 mm (0.59”) is referred to as 15/0. The length of insert blocks is always 60 mm (2.36”)
