Common Issues with Sunflex Bifold Doors

Even premium Sunflex doors can develop issues. Problems may arise from normal use or poor installation, which can cause long-term operational challenges.

​

Common issues include:

​

• Dropped or Sagging Panels – Worn rollers or misaligned tracks can cause panels to sag, particularly if installed off-level.

• Stiff or Sticky Operation – Debris, roller wear, or environmental factors can impede smooth operation.

• Worn Rollers or Wheels – Leads to uneven folding or dragging panels.

• Hinge & Pivot Problems – Misalignment from installation or building settling causes jerky movement and stress on hardware.

• Track Misalignment – Uneven or non-level tracks result in rubbing, dragging, or uneven folding.

• Locking Mechanism Issues – Multi-point locks may fail to engage correctly.

​

Toe and Heel Misalignment

A long-term issue often caused by installation is toe and heel misalignment, where the top (toe) and bottom (heel) of a panel are not perfectly level within the frame.

​

Signs:

​

• Panels appear tilted when folded or closed

• One side drags during operation

• Extra stress on rollers, hinges, and locks

​

Causes:

​

• Panels not leveled at installation

• Frames not squared correctly

• Building settling over time

​

How Pro-Lock Corrects Toe and Heel Misalignment:

​

• Realigning panels at both toe and heel points for smooth, even operation

• Adjusting hinges, pivots, and rollers to distribute weight evenly

• Correcting track alignment

• Providing maintenance advice to prevent recurrence

​

By addressing both regular wear and installation-related issues, Pro-Lock restores Sunflex doors to smooth, secure, and reliable operation.
