Max Tunnel Bow Sections

Not exactly... The Caterpillar Tunnel Max is only sold in 5-ft spacing configurations, but if you really want to have a 4-ft bow spacing tunnel, you can simply buy a slightly longer tunnel and install your bows closer together, except for the first 3 and last 3 bows. This will allow for your wind bracing to fit correctly. 
 For example, if you want a 48-ft tunnel with 4-ft bow spacing, order a 60-ft tunnel with 5-ft bow spacing and install the center bows closer together.
 

We have designed new 21-ft wide versions of the Framed Double Zipper End Wall and the DIY End Wall to for the Caterpillar Tunnel Max.

We don't currently sell an official roll-up sides kit for the Caterpillar Tunnel Max at this time, but you're welcome to DIY it yourself if this is important to you. There are many resources online to help get you headed in the right direction.

Thanks to the thicker diameter pipes, industry leading 14-gauge metal, and the Earth Lock anchor plates, the Caterpillar Tunnel Max has our strongest bow design yet, and the Earth Lock anchor plates at the corners keep it anchored better than any other method besides ground posts in concrete.

It depends on the width of your pathways. You can comfortably fit 6 beds with 12” pathways, and you could even manage to fit 7 beds with 8.5” pathways if you think the juice is worth the squeeze.
