Sliding Patio Door Operation and Roller Test

Inspection template for assembled sliding and patio doors to verify roller alignment, rolling force, smooth operation, and lock engagement before shipment.

Inspection Setup and Door Identification

• Door model, size, and serial/lot identification recorded
  Record the assembled door model, dimensions, serial number, and production lot or work order.
• Inspection performed on fully assembled door unit
  Confirm the door is fully assembled with rollers, track interface, and lock hardware installed.
• Inspection area clean and door accessible for full travel test
  Confirm the test area allows the door to travel its full range without obstruction.

Roller Alignment and Track Condition

• Rollers seated correctly and aligned to track
  Verify both rollers are properly seated, aligned, and contacting the track evenly.
• Roller adjustment is within specification
  Confirm roller height/adjustment is set to achieve proper door alignment and travel.
• Track surface free of debris, damage, or burrs
  Inspect the track for debris, dents, rough spots, or burrs that could cause binding or uneven travel.
• Door panel remains plumb and square during travel
  Observe the panel during movement for visible racking, tilt, or uneven gap changes.

Rolling Force and Smooth Operation

• Opening force measured within acceptable range
  Measure the force required to initiate and sustain door movement. Record the value used for the test.
• Door travels smoothly without binding, sticking, or chatter
  Move the door through full open and close travel and confirm smooth rolling with no binding, sticking, or abnormal noise.
• Door closes fully and returns to proper seated position
  Confirm the door reaches the closed position without rebound, interference, or incomplete seating.
• No abnormal noise, vibration, or scraping observed
  Listen and observe for grinding, scraping, rattling, or vibration during operation.

Lock Engagement and Security Check

• Lock engages fully and secures the door
  Verify the lock or latch engages completely and holds the door in the closed position.
• Lock operation is smooth and requires normal actuation force
  Test the lock several times to confirm consistent engagement and release without excessive force.
• Keeper/strike alignment is correct
  Confirm the lock keeper or strike aligns with the latch and shows no visible misalignment or wear.

Final Quality and Release

• Visible defects documented and dispositioned
  Record any non-conformance such as scratches, dents, misalignment, or hardware issues and note the disposition.
• Door approved for shipment
  Confirm the door meets operation and lock requirements and is approved for release.
