Smart Systems Visofold · Aluminium · 4 panel
A four-panel aluminium Smart Systems Visofold doorset in Attleborough was reported with panels catching the frame and difficulty locking. The assessment recorded mild frame distortion. It was within the manufacturer's tolerances, so panel alignment was the correct route to counter it rather than any frame work, and the existing rollers were catching the frame through a combination of that distortion and their own design. The repair replaced the failed top and bottom roller hinges, realigned all four panels and serviced the components.
