The new Series 412 bi-fold door panels from Architectural Window Systems
roll on Centor stainless steel bearing rollers, and they are able to support door panels of up to 80kg.
A flexible sill flap conceals the rollers and prevents dust and water from coming into contact with the sill track, which helps to ensure the doors operate smoothly and without trouble.
A semi-rigid PVC guide track reduces noise, while door panels can be adjusted to accommodate building settlement.
Series 412 bi-fold door panels are available with a variety of lever and lock options.
