Powell split frames
These fit inside a box of 110mm/190mm and 94-100mm deep. Each half takes around 11 hours to make. Once your used to using these you can create a new colony in 1 minute, once your first frame is full. Minimal damage is caused to the colony allowing a fast bounce back post split. These frames can be used with all Austroplebeia; Symei, Cockerelli, essingtoni, ornata, websteri, percincta, cincta and of course australis if you prefer to call them all that. I believe these will also work very well with Tetragonula Sapiens and clypearis as I have had time to observe both these species in boxes and in their wild environments.
Two halves cost $40 with free shipping within Australia.
