Abstract

An in-line fastener track selection device comprises a stator having first, second and third fastener conduits; a rotor, rotatably mounted with respect the stator about a rotation axis, and comprising a rotor body and a connection space. The rotor is rotatable between a first position in which the connection space adjoins the first and second fastener conduits, such that, in use, a fastener may pass between the first and second fastener conduits via the connection space, and a second position in which the connection space adjoins the first and third fastener conduits, such that, in use, a fastener may pass between the first and third fastener conduits via the connection space.
