IB GZ 18 Swift entrance stone

This entrance cylinder for swifts is highly versatile and can be used in combination with our Swift built-in nest boxes IB GZ 04 and IB GZ 06, for example. The cylinder can be easily installed through the façade cladding, providing access to the built-in block. The large round flange ensures a neat finish on the exterior wall. Additionally, the cylinders can also be used directly in eaves cladding, allowing the birds to nest in the eaves, with or without a nesting box placed behind the cylinder.
