Start with the equipment you own
Identify that code system from the equipment documentation before treating the row as relevant. Find the model label on the opener motor housing and note the technology marking. If the label is missing, the official support page is a better next stop than a guessed purchase.
What is verified here?
The current research has no separate branded accessory SKU card for this maker. The relevant entry is in a specific universal remote chart, so its scope stops at that listed protocol. Check the original opener manual for an exact model answer.
Where a brand match stops
Two openers can carry the same logo while using different radio systems. That is why our finder asks for a LEARN-button family or a named protocol and keeps unverified cases visible instead of presenting a shopping result.
