Details of Crown board with 4 cm feeding eke and ventilation

4 cm

EKE FRAME

3 cm

USABLE INNER GAP

Hardboard crown board with a 4 cm pine eke and a central vent: it lifts the roof and leaves room to feed.

It works as an ordinary crown board and, on top of that, as a spacer: the perimeter frame leaves 3 cm of clearance between the top bars and the outer roof — exactly the room a syrup bag or a crown board feeder needs.

01 · THE PROBLEM IT SOLVES

With a flat roof, a syrup bag stops it closing

If your hive runs a shallow outer roof — flat metal ones and budget covers — putting a syrup bag over the frames leaves the roof sitting proud. And that is where the same three problems start: water gets in, robbing gets in, and bees get crushed on closing. This crown board lifts the roof by 3 cm and gives you the room for emergency feeding, winter candy, a syrup bag or an inverted rigid feeder.

02 · THE VENT

Ventilates in transport and doubles as a feeder port

It has a plastic disc with a grille and a tab built into the centre. It ventilates on short moves or hot days without letting bees out, and it works as a port for fitting a rapid feeder right over the hole. If you would rather keep it shut in winter, laying the bag or the feeder on top blocks it — no extra parts.

03 · WHICH SIZE?

Look at your frames' top bar, not at the hive's brand

510 × 425 mmLangstroth and Dadant US. One size serves both formats, and it is the common one in Spain.
500 × 425 mmDadant Blatt, the French size. One centimetre shorter; get it wrong and it rattles on the box.

04 · BEFORE YOU BUY

Hardboard base — a smooth surface, so they do not propolise gaps — and a solid pine frame jointed on all four corners, which is the part that takes the weight of a loaded roof and the leverage of the hive tool prising it off the propolis.

✓ FITSLangstroth and Dadant US (510 × 425 mm) or Dadant Blatt (500 × 425 mm), by version.
⚠ NOT INCLUDEDFeeder or syrup bag: the crown board makes the room, the feed is separate.

Would is cheap quality and damp appeared over the winter in less than two months on the largest surface. The outer edges were painted but condensation from the colony resulted in black mould forming around the feeder hole and across the crown board on both the upper and lower surfaces. If you buy these, treat them against the mould like you would a hive.
