(1) Sections: Steel panels reinforced with stiles interconnected with hinges and rollers. You can replace sections without having to replace an entire door.
(2) Bottom Brackets (AKA Bottom Fixtures): Structured supports at the bottom of a garage door that provide for attachments of lifting cables.
(3) Cable Drums: Grooved drums on the torsion spring shaft that allow lifting cables to wind when garage doors open.

Notes Regarding Garage Door Springs: If a garage door does not open, a damaged spring is the most common problem. Garage Doors will either have torsion springs or extension springs. The above example includes both just as an example. Only attempt to repair or replace garage door springs if you are a trained professional. Springs are the most dangerous component on a garage door. Springs generally last 8-10 years on a residential home.
