Plastic rail for Segeberger polystyrene beehives.
 Made of plastic and suitable for 11 windows, this rail is 9 times reinforced at the back.
 It provides a deeper contact surface and is intended for the brood chamber frame when a queen excluder is placed over it.
 This places the brood chamber frames 8mm lower below the grid at the top, preserving the bee space from obstruction.
 The length is 41 cm.
