Plastic 8-way escape

Plastic 8-way escape,made by plastic,yellow colur
      The 8 way Bee escape is injection moulded in white plastic,
It is circular, 258 mm in diameter. The volume of space that it encloses is an eight pointed star. Each outlet nozzle is 7 mm wide by 6 mm tall. The "points" of the star are 70 mm long and taper from 12.5 mm, the central body of the star has 32 holes 3 mm in dia. These plastic inserts are screwed to the underside of a plywood board that has a central 33 mm hole. There are 8 fixing holes provided, but I have found that after some years of use, (I have used this type for about 24 years and have about 40 of them), the plastic tends to buckle so I have drilled extra fixings in mine as indicated by the red holes in the drawing and now ignore the original holes.
