Manual selection questions

How do I choose the right Linear document?

Copy the complete model number and manufacture date from the opener label. Match the manual revision, region, and controls to that unit. Similar housings or nearly identical model numbers do not establish compatibility.

Is a brochure the same as an installation manual?

No. A brochure describes product choices; an owner guide covers operation and routine checks. Installation and service documents cover equipment setup. Use the document intended for your task, and have spring, cable, structural, and powered-door work assessed by a qualified technician.

Why do some links open a support page instead of a PDF?

Manufacturers may offer multiple languages, revisions, or downloads on one support page. We label those destinations as manufacturer support rather than calling them PDFs. Select the document that matches your equipment on that page.

Does this include every Linear model ever sold?

No. This catalog covers records found in the listed official sources. Historical regional variants, accessories, and restricted downloads may be absent. A record is not a statement of current stock, warranty coverage, or replacement-part compatibility.

Can D&L help if I cannot identify my equipment?

Contact D&L with a photo of the equipment label and an overview of the door or opener. Our team can help establish the next step and discuss an inspection or replacement. Do not remove covers or disturb spring hardware to find a label.
