The Schwegler Swift Observation Box 15 is designed to be built into an external wall with the entrance hole at least 5m from the outside ground. The side with the entrance hole is set flush to the outside wall surface and can be painted or rendered if desired.
Activity inside the box is seen from inside the building by simply unlocking and opening the observation flap and looking through the transparent plastic window (which itself can be removed for cleaning). A Nest Mould, which encourages nesting, is also included.
Siting: ideal for unheated rooms, roof spaces, elevator shafts, etc. The access hole through the exterior facade is only 30x70mm.
Material: Schwegler wood-concrete
Interior dimensions: height 17 x width 36 x depth 16 cm
