Schwegler 2FR Bat Tube/Access Unit

The Schwegler 2FR Bat Tube/Access Unit is a built-in bat roost designed for installation within the masonry of an external wall. It can be built in flush with the wall or installed beneath a rendered surface, making it suitable for new-build, conversion and renovation projects.

The 2FR is a modular version of the Schwegler 1FR Bat Tube. Unlike the 1FR, it includes optional transverse connecting holes, allowing several units to be installed side by side to create a larger connected roosting space. Schwegler recommends joining at least three units per roost.

An optional passage through the rear panel can also be opened to allow access to existing wall cavities or building roosts. This makes the 2FR particularly useful where access to existing roosting spaces needs to be retained during renovation or conversion work.

Siting & Installation

The Schwegler 2FR is designed to be built into external walls, either flush with the masonry or beneath a rendered surface. It can be used as a single access unit, but is best suited to projects where several units are installed together to form a larger connected roost.

To connect multiple units, the preformed sections in the side panels can be gently knocked out to allow bats to move between adjacent tubes. If access to an existing wall cavity or building roost is required, the rear passage can also be opened.

Install at least 3m above ground level. A position that receives some sun during the day is recommended, particularly where the unit is close to existing bat activity, feeding areas or flight routes.

Where access to an existing building roost or wall cavity is required, multiple Schwegler 2FR units are recommended rather than the standalone 1FR Bat Tube, as the 2FR includes optional side and rear passage connections.

Maintenance

The 2FR requires no routine maintenance. Droppings fall out through the entrance ramp, helping to keep the roost clean.
