It's made out of heavy duty plastic; purchased it at Linen's but you can get one at Bed Bath or any warehouse club - I paid $79 for mine - end of season sale. There are variious sizes for deck boxes from small to large. I have a large box.

My husband used a jig saw and it was easy - the openings are adequate but certainly not framed or precision cut!

I have a litter box in the garage that the cats access thru a pet door that I have in the door going out to the garage. I suspect they use this when it's stormy out because I always scoop this box even when it's not stormy! They do come running in from the lanai when it's thundering.
