We offer an inline, out-of-sight bi-folding door track system. This track system is strong and secure.
The system can be incorporated into a cill, but is supplied flush as standard. All our running gear is concealed, making it resistant to attack from potential intruders.

Some people prefer a step on the inside and outside, some prefer a step on the outside only, but many prefer a flush threshold which blends the inside floor with the outside floor. This is especially desired when there are children, elderly people or wheelchair users, to reduce the risk and maximise accessibility.
