Guardian / Garage door opener / Model guide
Match Guardian 728B to its listed STDBAT battery, GUDT-319 holster, GUDT-349 motor and GUDT-353 opener cover using the official parts book.
Identifier: 728B. Keep every letter and suffix on your product label when checking applicability.
For 728B, the book lists STDBAT as the portable battery and GUDT-319 as a battery holster. These rows retain separate identifiers and do not establish that STDBBUKIT or a generic battery is interchangeable.
The assembly references include GUDT-349 for the DC motor, GUDT-322 for the logic board and GUDT-353 for the opener cover. The book places a qualified-technician replacement requirement after this model’s assembly table.
The accessory section names R2BCC and 3-FDCC. Read the exact 728B heading in the DOCX parts book before applying any listed component to a unit.
