Keep the interior of your existing Purple Martin Barn bird house strong with these S&K Attic Divider Panels. These 3, specifically shaped, corrugated plastic panels create the top floor of your existing S&K Purple Martin Barn, turning it from an open chamber into 4 separate compartments for martins. The generous, flat rectangular piece creates the attic floor, and perforated slots in it help you properly place the other dividers. Tabs on the base of the narrower rectangular section insert into these slots, keeping this divider upright and halving the floor along its length. The last panel evokes a bell curve, and intersects the upright panel to align with the roof line. A vertical slot in the center of these walls allows them to interlock in the exact right spot, for perfect placement within the martin house frame. Ensure the top of your existing Purple Martin Barn maintains 4 separate nesting chambers with these Attic Divider Panels for the BN-16 Purple Martin Barn. Made in the USA.
