B.S. Commercial Bee Hive Frame Bottom Bars

Tolerances are + 0.1 mm   Material... Most softwoods are suitable.

Third Angle Projection, American Projection

Like all wooden frames intended for use in bee hives, there are many variations... The types illustrated below are the most common.

I do not recommend the 8 mm x 6 mm version as it is too flimsy and can warp badly. The twin Manley type is probably the most common, certainly I was asked for them most often when I was in the beekeeping equipment supply business.

there is a 22 mm wide single version that is similar in all other respects to the one at the bottom of the drawing.
