Function and service checks

Inspect for rubbing, lateral movement, cracked guide surfaces, loose fasteners, or uneven closing contact. Check track alignment before assuming the guide alone is at fault.

Compatibility and replacement planning

The manufacturer catalog lists door families Slide. These are door types, not verified equipment model numbers. Match OEM part 4000-05L to the installed assembly; fit is not confirmed for every door in these families.

Match leading versus trailing edge, left/right travel, and the mating rail or hook arrangement. Match OEM part 4000-05L to your service records. Appearance or door size alone is not enough to establish fit.

Before you order

Compare the installed part, mounting pattern, and measurements. Have the door serial number and clear photos ready for fitment help.

The displayed price is for one linear foot. Quantity represents the number of feet. Confirm the required cut lengths before ordering; a multi-foot quantity does not by itself confirm one continuous piece.
