International Sourcing of Obsolete APG Components

Commercial Door Maintenance and Security Ltd were instructed to attend a KIKO Milano store within a busy Bristol shopping centre after their extremely large APG glass entrance doors began to fail. Upon inspection, our engineers identified that the overhead roller system was faulty and beyond repair. Complicating the situation further, the specific roller assembly was obsolete and no longer available through standard UK or European supply channels. Given the size and weight of the glass panels, the failure had caused the door to drop slightly, placing additional strain on the track and creating both operational and safety concerns within a high-footfall retail environment.

Recognising the importance of preserving the existing door system rather than replacing the entire installation, we initiated a global search for the correct roller kit. After extensive supplier liaison, we located a manufacturer in the United States who had just five remaining units left in their worldwide inventory. These were traced to their German branch, allowing us to secure one kit with a three-week turnaround. Acting decisively ensured the client retained their original APG door system without the significant cost and disruption associated with full replacement, demonstrating our persistence and international sourcing capability when dealing with discontinued specialist components.

Out-of-Hours Installation of Large Glass Door Panels

Once the replacement kit arrived, our engineers scheduled the works outside normal trading hours to ensure the safety of the public and to minimise disruption within the shopping centre. The APG doors were exceptionally large, heavy glass panels requiring particularly gentle and controlled handling throughout the process. Extreme care was taken to support the door leaf correctly while removing the track canopy to gain access to the overhead roller assembly. The faulty roller was carefully dismantled and replaced with the new system, including new carriages and wheels, ensuring proper weight distribution and alignment across the track.

In addition to installing the new roller mechanism, we replaced the gasket and carried out detailed adjustments to the door stops to achieve precise clearance and smooth travel. Due to the scale and fragility of the glass panels, alignment tolerances were critical, and our engineers methodically balanced and tested the system to ensure flawless operation. The door is now fully lifted clear of the floor and operating correctly, smoothly and safely. This project highlights our expertise in handling large-format glass entrance systems and delivering complex repairs with professionalism, precision and care.
