I'm planning to build my first snake rack. I'll be using 3/4 inch melamine for the sides and shelves, not sure what I'm going to use for the back yet but it'll probably be 1/4" thick.

Anyways the issue I'm having is that since my sides will be fully enclosed I'm not going to run the 4" FlexWatt across the back of each shelf...Instead, I'm wondering if it will be ok to run one 11" strip vertically attatched to the back panel. Do you guys think this will work just as well as the 4' pieces under the tub?

Thanks.
