Actually, I do also sell a 2x6 coro bottom if you'd like. It's just that the box necessary to ship falls in the "oversize 2" category for UPS. You can email me with your zip code so I can get you an accurate shipping cost if you'd like. [email protected]. It's all one piece, actually.
Can you buy coroplast in your area? The sheets I buy at the local print shop are 8 feet long. They said that is the size from the manufacturer? My 2x6 cage was the perfect fit for it. Plus all the sides have a 5 inch flap.
