Compatibility with TOP bee space National equipment is assured. Compatibility with Standard National Parts can be achieved either by assembling the parts differently or by adding a 9 mm x 12 mm rim.

These Items can be assembled for TOP BEE SPACE use or BOTTOM BEE SPACE as required by the individual.

They were all designed by Dave Cushman during the 1080s and 1990s, whilst he was proprietor of APEX ENTERPRISES. Each item offers some benefit over more conventional designs, either in terms of ease of assembly, durability, function or bee productivity.

Never mix this type of equipment with 'Standard National' equipment as the bee spaces between boxes and frames will be compromised resulting in extra comb and propolis where you do not want it.

The "RATIONAL" system detailed here has nothing in common, apart from Top Bee Space, with the system that was proposed during the 1970's.
