Metal corner joint for hive to connect the brood nest and the super. It is advisable to use 3 joints for each hive, two in the front and one in the back of the hive brood nest. The fourth corner (free) is used to allow the insertion of the hive tool when it is necessary to raise the crown board (or the super). A tool-rest joint may be inserted in the fourth corner to prevent the hive tool from damaging the wood.
Perforated metal sheet for anti-varroa mite base. It allows varroa mites to fall down during the treatment. Unlike the net, metal sheet is more comfortable for the bees, which can walk on it and do not cover it with propolis.
Galvanised metal sheet drawer to be fitted in the anti-varroa bottom to collect varroa mites during treatments.
