Guardian 928CC parts and component reference

Identify Guardian 928CC controls, lock-related hardware and assembly numbers, including B5A928, GU-CTM, GU-LOCK2 and GUDT-378, from its official parts-list section.

Match the model before choosing a document

Identifier: 928CC. Keep every letter and suffix on your product label when checking applicability.

The 928CC installation/accessory table identifies B5A928 as a 12V 5Ah battery, enclosure and hardware kit. It separately lists GUDT-359 as a 12V 5Ah battery. A matching electrical rating does not turn these two identifiers into aliases.

The same section lists GU-CTM as the cable-tension monitor, GU-LOCK2 as the door lock and GU-LOCKX as an 8 m service-lock extension cable. These are model-scoped component references, with no inferred lock-to-cable or monitor-to-board connection.

The assembly section names GUDT-378 as the receiver and logic board, GUDT-366 as the control-panel cover and GUDT-368 as the chassis cover. GUDT-358 appears in both tables and remains one emergency-release cord identity in this model lookup.

Before applying these details

  • No V3 pairing or negative V3 compatibility claim is made for 928CC from its absence in this table.
  • GUDT-387 has a source position quantity of two; that is not a claim about pack quantity or availability.
  • The 8 m GU-LOCKX length is the reviewed source value; it does not establish compatibility with a separately named lock by inference.
  • A listed component does not establish that it is installed, available, interchangeable with another revision or approved as a replacement for a different part number.
  • The source provides part references for this exact model. Opener power rating, door capacity, dimensions and a current installation manual are not established by this parts-list review.
