UK Equipment Supplies World Equipment Supplies		"A-Z" INDEX &   SEARCH Castellated Spacers for Beehive frame spacing

Sheet metal plates with rectangular cut-outs that can be used in beehives instead of frame runners to achieve an accurate spacing of frames.

All Notches are 22 mm wide and 9 mm deep.

These are designed for B.S. National Hives.

The strips are 420 mm long, 28 mm wide with 1.5 mm fixing holes.

I usually drill 3 extra fixing holes as I find that with only 4... the strips tend to bow between the fixings, due to seasonal shrinkage and expansion. The 12's and 13's are used in mating nucs in an attempt to reduce the possibility of drone production. The 12's are also used in extra shallow (75 mm tall) ekes with top bars and starter strips... for cut comb production (and also to satisfy the bees need for comb building).

There is another, shorter style of castellated spacer that is made in 10's, 9's and 8's spacing to suit the nominally 10 frame WBC type of hive.

I use 19 mm black parkerised gimp pins to fix the strips and I use a spacing jig to ensure accurate depth of placement (I use Top Bee Space).

The material used is 28 SWG Zintec coated steel sheet and they can be purchased from B.J. Engineering.
