TL;DR
A chain-drive opener is a garage door opener that pulls its trolley with a bicycle-style roller chain along the rail, the oldest and most rugged of the common drive types and typically the least expensive. The chain tolerates heavy doors, temperature swings, and decades of cycles, which keeps it the default for detached garages and oversized or solid-wood doors where its metallic rattle bothers no one.
What it means
A chain-drive opener is a garage door opener that pulls its trolley with a bicycle-style roller chain along the rail, the oldest and most rugged of the common drive types and typically the least expensive. The chain tolerates heavy doors, temperature swings, and decades of cycles, which keeps it the default for detached garages and oversized or solid-wood doors where its metallic rattle bothers no one. Maintenance is minimal: chain tension checked so it neither slaps the rail nor binds, and a light coat of garage-door lubricant periodically.
