Function and service checks

Inspect for a torn or hardened seal, a loose retainer, or gaps at the door edge. Door alignment and damaged mounting surfaces can also prevent an effective seal.

Compatibility and replacement planning

The manufacturer catalog lists door families Slide, Vertical Lift, Sectional. These are door types, not verified equipment model numbers. Match OEM part 1303-89 to the installed assembly; fit is not confirmed for every door in these families.

Compare the profile, mounting arrangement, and required length with the existing seal assembly. Match OEM part 1303-89 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.
