I realised I made a mistake with the gates. So I have corrected my error.

Now to actually have a full enclosure you have four different gates to use. 2 inch, 1.5 inch, 1 inch, and 0.5 inch. This will allow you to use different door configurations. I still need to work on the big old 6 inch gate yet.

A 2 inch gate end with a 2 inch gate.

A 1.5 inch gate end with a 3 inch gate

A 1 inch gate end with two 2 inch gates

A half inch gate end with a 3 inch gate and a 2 inch gate
