Camper Van Buddy Box for the Thetford 335 Porta Potti? Due to the Russian birch ply being taken out of the market we have had to increase our costs to cover the increased cost of Birch ply. High Quality Birch Ply. Unlike most other cover boxes used for toilet storage, our Buddy Box’s are made from high quality 15mm birch ply wood which ensures longevity, durability and strength. All surfaces are sanded smooth, ready for any colour or varnish you may wish to add, or leave as is. All parts have been precision cut using a CNC machine, guaranteeing accuracy and consistent product quality, every time. Our Buddy Box’s come complete with piano hinges and two sleek 100n gas struts, to help ensure safety and ease when opening and closing your buddy box lid. Designed for Accessibility and Convenience. Our Buddy Box’s are designed not only to look the part, but also to make your life as easy as possible. The large cutout at the back of the box helps you to gain easier access to your Porta Potti, making the process of emptying, much more convenient. Finally, our boxes come already assembled, which means upon arrival, simply unpack and you’re good to go! Porta Potti not included. Overall exterior product dimension is 420mm width, 430mm depth and 341 mm height.
