CLEANING DOOR TRACKS
The bi-fold door mechanism is contained in
tracks at the top and bottom of each door. To
ensure optimum operation, the tracks must be
kept clear of debris at all times.
1. Do not allow liquids to collect in the tracks.
2. Clean tracks at least weekly:
• Remove door bumpers from tracks to
ensure complete cleaning.
• Use track wipe-outs, located at the center of
each track, when cleaning.
• Use soap and hot water with a brush to
remove accumulated debris.
3. If necessary, the bi-fold
doors may be opened
fully. Pull the upper and
lower pins to release
center doors from track.
Be sure to seat the pins
fully when returning the
door to the track.
4. Replace door bumpers
after cleaning.
5. Do not add lubricant to
the door mechanism.
