Slanted roof nest box made from 15mm gauge Fir. The Multi Nest Box comes with 3 interchangeable entrances: 25mm and 32mm diameter holes, and an open front. To change the type of box, simply screw the panel with the selected hole size to the top section of the front (using the screws included). Alternatively, leave the two panels off for an open-fronted box. The roof overhangs the front of the box, providing protection against the elements and predators at the entrance hole. A separate plinth is included, which can be screwed to the back of the nest box (3 screws supplied) and which can be used to fix the box to a tree. Nest box finished with a clear and safe preservative.
