Slotted Trays
When selecting trays, pay close attention to the width of the tray and make sure that it suits the frame you have.
There are two widths, 950mm wide (which suits the 1000mm wide frames, VK4FR & VK5FR) and 630mm wide (which suits the 685mm wide frames (VK1FR & VK3FR).
Once you have picked the trays you want, don't forget to get the plastic bins to suit.
