In the British National Drawhive, the frames fit parallel with the opening side panel. The capacity is the same as the standard item.
In hives with short frame lugs, such as Dadant & Langstroth, the frames fit at right-angles to the opening side panel and there is a loss of one frame compared to the standard item. There is, however, room for a thinner dummy frame.
Materials: Because dimensional stability is critical to the success of the Drawhive, they are designed to be constructed in WBP grade plywood.
Some narrow sections, such as rack frames, are in solid timber and there is some stainless steel along the ends of the frame lugs.
Marine grade adhesive is specified and all fixings are stainless steel or brass.
Support slides are rated to carry 45 kg. They are zinc plated steel and greased to lubricate and prevent corrosion.
