Designed to be versatile, sturdy, and easy to use; this bottom board is stand alone. It needs no other bottom boards or add-ons to function. a 1/8" mesh screen covers the entire floor allowing for the greatest ventilation and mite drop possible. 3/8" or 3/4" strips around three sides provides the entrance of your choosing. A white vinyl-coated masonite tray slips in the back (or front if you specify) on a track below the screen for easy mite count access. By using 1 3/8" stock for two interlocking frames we have achieved a very strong durable construction.
Since it is not necessary to have a mite tray for every bottom board they are ordered separately.
