'B Grade' Poly - grab yourself a bargain. A collection of poly hives and hive parts that don't make the usual expected grade. All will be perfectly usable but may have a few extra dents, cracks or nibbles than usual.
An extension for the poly nuc hive allowing the use of 6 super frames (SN4 or SN1). These can be stacked as high or as many as you like and allow better and easier management of your nucs or small colonies. Can be used in conjunction with the brood box for poly nuc and the top style feeders
