This bat slope is designed to be used in conjunction with the Schwegler 1MF bat and swift nest box. By using the bat slope, the 1MF nest box can be built directly into the brickwork of a wall, with the box flush with the face of the wall. The bat slope still allows access to the rear for bats. This is often preferable for listed buildings or for other architectural reasons. The Bat Slope is fixed in place first and the 1MF then positioned above it.

Schwegler nests will last decades and are readily adopted by birds and bats. This means decades of breeding success in real life conditions. These nest boxes have been developed in close collaboration with leading ornithologists, nature conservation organisations, Government conservation agencies and forestry experts, and are backed up by decades of experience and knowledge. In each nest box the size of the brood chamber, diameter of the entrance hole and many other features have been adapted to the needs and behaviour of the animals themselves. Experiments by bird protection organisations worldwide have demonstrated that the highest density of bird populations (i.e., breeding pairs per hectare) is achieved with Schwegler nest boxes.
Schwegler nest boxes have been officially recognised and approved by the following organisations and numerous others worldwide:
German Federal Biological Centre for Agriculture and Forestry (BBA)
German Nature Protection Association (NABU)
Bavarian Regional Association for the Protection of Birds (LBV)
German Environmental Protection Association (DUH)
Jordsand, Society for the Protection of Seabirds and Nature
EURONATUR/European Cultural Heritage Foundation
Luxemburg Association for the Protection of Birds and Nature
Blue Bird Association of North America
