Wanted to give a recommendation for anyone looking for a nice HDPE enclosure. Jim and Anna from Next Level Displays were at the Show Me Snakes show in Janesville, Wi. and had units ready to purchase and carry out. Very nicely designed and easy to get into if you need to install heaters or lights. I purchased the 48x24x16" dual flip doors enclosure and really like the design and the CNC cuts. Totally worth a look.
