Much lighter than metal excluders which makes them easier to carry, install and collect at the apiary. Perfect gaps that do not injure the bees. Just 3 mm thick so that the floor connectors can be fastened.
Also available with integrated plastic frame with entrances (ref. AN51405) that allows addition of a second excluder, to combine two queens in the same hive. Resistant to oxalic or formic acid, or even steam (up to 119oC).
