With this extension, you can turn a standard beekeeping frame into a Hoffman frame. It therefore does not need classic cylindrical spacers and is double-sided (orientation does not matter). The spacer usually sticks to the frame on its own, but I recommend attaching it with screws or nails (2 pcs per spacer should be enough).
Designed for a frame thickness of 24 - 25 mm.
Optional material: (2-4 pcs of 3x10 mm wood screws or nails / spacer -> 4-8 pcs / beekeeping frame)
