- Torsion spring
- A heavy-duty steel spring mounted on a metal shaft above the garage door opening. It stores mechanical energy by twisting tightly as the door closes and unwinding to help lift the heavy door. When answering what is a torsion spring, experts note it is under extreme tension; for safe replacement, check out our torsion vs extension spring guide.
- Extension spring
- A pair of long steel springs that stretch and contract along the horizontal tracks on either side of an open garage door. They counterbalance the weight of the door. If one snaps, both should be replaced simultaneously to maintain balanced tension and prevent premature failure.
- Track
- The heavy-gauge vertical and horizontal steel assemblies that guide your garage door rollers smoothly up and down. If your door binds, jams, or leaves the path during stormy Westerly weather, you might need a professional realignment to avoid replacing the entire assembly.
- Roller
- The small wheels—made of nylon, steel, or plastic—attached to the edges of your garage door panels that travel inside the metal track. High-quality nylon rollers with sealed ball bearings drastically reduce operational noise and outlast basic steel alternatives.
- Opener
- The motorized unit mounted to your garage ceiling that automatically raises and lowers the door via remote control, wall switch, or smartphone app. Modern units feature belt, chain, or direct-drive mechanisms designed for smooth, reliable everyday operation.
- Photo-eye sensor
- A vital safety device featuring two small electronic units positioned near the bottom of the tracks, facing each other. They project an invisible infrared beam across the opening; if anything interrupts this beam while the door closes, the door automatically reverses.
- Limit switch
- An internal electronic or mechanical adjustment on your garage door opener that tells the motor precisely when to stop running. Correctly set limits ensure your door closes fully to the ground without crushing the seal or stopping short of a complete closure.
- Weatherstripping
- The flexible rubber, vinyl, or brush seal affixed along the top, sides, and bottom of your garage door frame. It blocks bitter New England winter drafts, heavy rain, and pests from entering your garage, protecting your stored belongings year-round.
- R-value (insulation)
- A standard measurement rating thermal resistance; a higher R-value means superior insulation performance. For uninsulated garages attached to Westerly homes, upgrading to a higher R-value door keeps utility bills lower and prevents freezing winter temperatures inside.
- Cable drum
- The grooved aluminum wheel mounted on the ends of the torsion spring shaft. As the door moves, these drums wind or unwind the heavy steel lift cables that physically support the bottom corners of the door panels.
- Bottom seal
- A flexible rubber or vinyl strip attached directly to the bottom panel of the garage door. It compresses against the concrete floor when closed, creating a tight weather barrier against wind-driven rain and snowmelt common in our coastal area.
- Travel module
- The specialized electronic component inside automatic garage door openers that tracks the exact rotational distance the motor travels. It works in tandem with limit switches to ensure smooth, precise positioning every single cycle.
- Trolley
- The sliding carriage mechanism attached to the opener's drive chain or belt that physically connects the garage door arm to the motorized rail. It pulls and pushes the door open and shut during every operation.
- Manual release
- The red-handled cord hanging from your automatic garage door opener trolley. Pulling it disengages the opener from the door mechanism, allowing you to safely open or close your garage door by hand during a power outage.

Westerly homeowners often get confused because unscrupulous contractors use complex technical jargon to upsell unnecessary parts.

What is the most misunderstood spring term when local residents call our Watch Hill and Bradford service routes?
