The commercial hive is a popular hive often used with national supers to give the queen a bigger laying area, there is a 4mm difference overall in the external box sizes but it is hardly noticeable and has not affect on the working of the hive. Our commercial hives are made from top quality Canadian Cedar.
Commercial hives are very easy to construct having only 4 components. They have small hand holds cut into the side of the box for lifting, unlike the national that has big rails. The frames lugs are shorter which gives a bigger area of wax comb for the queen to lay. They are bottom bee space and can be used with commercial or national supers.
