Linear LDCO850 and LDCO852: choose the correct homeowner manual
These Wi-Fi opener models have separate manuals and both list included battery backup.
Match the model before choosing a document
Identifier: LDCO850 / LDCO852. This guide compares a family or related models. Use the exact configuration on your label.
Models covered: LDCO850, LDCO852. They are separate configurations; compare the applicable facts and documents below.
Use the LDCO850 manual for 850 and the LDCO852 manual for 852. They are separate documents with different identifiers.
The manual index supplies LDCO850 Rev E, while the product page links an older Rev D. Revision date is evidence about the document, not a product manufacture date.
Before changing rails, ask Linear to confirm the exact configuration: both product pages mention 10-foot rails but give an 8-foot maximum in their dimension section.
