Ive been trying to call they guy I usually get my retile supplies from but he hasn't answered for a week straight and I need to know the answer already.

Ok so I've just finished constructing a new rack for my snakes. It's constructed out of melamime and each shelf is exactly 6 1/4" above the last. I want to use 4" flexwatt heat tape doubled up on each shelf. But I need to know how to connect the pieces together on the same shelf and how to connect each shelf together so they all go to one power source. If my "doubling up" is hard to understand please let me know I'll clarify that for you, I didnt explain cus I don't wanna make this an essay.
