Canopy vs retractable gear on up-and-over doors
A canopy-gear up-and-over door has its springs on the head of the frame, tilts out and up, is cheaper at around £995–£1,900 installed, and is limited to roughly 2438mm wide with poor automation reliability. Retractable gear has springs on both sides, slides fully inside the garage, handles widths up to around 5m, and is the correct choice for any door you plan to automate.
The gear type is the single most important spec on a UK up-and-over door — it decides the maximum width, how well the door automates, and how much of the garage ceiling stays clear.
What canopy gear is
Canopy gear carries the door's springs and pivot arms mounted on the head of the frame, above the opening. As the door opens, the top of the panel tilts outward before swinging up, and roughly a third of the door still projects out over the drive when fully open. Canopy gear is the cheaper, simpler mechanism, but UK manufacturers generally cap it at around 2438mm wide because the leverage on a single-point head spring becomes unmanageable beyond that.
What retractable gear is
Retractable gear has springs and a track running along both sides of the frame, and the whole door slides back and up so it sits flush against the garage ceiling with nothing projecting over the drive. This side-mounted spring arrangement handles far more load, which is why retractable gear is used on wide single doors and is mandatory on virtually all double doors up to around 5m.
Automation — the deciding factor
If the door is going to be electric, retractable gear is the correct specification. Canopy gear's geometry — the door swinging outward before it clears the opening — puts uneven strain through a standard operator arm and is a common source of drifted limits and operator wear reported by UK installers. Retractable gear moves in a single, controlled vertical-then-horizontal path that a standard operator drives reliably, which is why it is the default gear for electric up-and-over doors and the only sensible choice on a double.
Price difference
Canopy gear is the budget option and keeps a manual steel up-and-over door around £995–£1,900 installed. Retractable gear costs more because of the extra hardware on both sides of the frame, and is standard on the £1,500–£2,500 electric up-and-over bracket. The price gap narrows once you add an operator, because canopy doors that are automated often need the operator reinforced or replaced sooner.
| Factor | Canopy gear | Retractable gear |
|---|---|---|
| Spring position | Head of the frame only | Both sides of the frame |
| Max practical width | Roughly 2438mm | Up to roughly 5m |
| Door position when open | Projects out over the drive | Sits flush against the ceiling |
| Automation suitability | Poor — uneven strain on the operator | Excellent — the standard for electric doors |
| Installed price (manual, single) | £995–£1,900 | Similar bracket, higher on wide/double doors |
| Best use case | Narrow manual doors, budget projects | Any door to be automated; all doubles |

Questions people ask
- What is the maximum width for a canopy gear garage door?
- UK manufacturers generally cap canopy-gear up-and-over doors at around 2438mm wide. Beyond that the single head-mounted spring cannot handle the leverage safely, so wider openings and all double doors use retractable gear instead.
- Can a canopy gear door be automated?
- It can be fitted with an operator, but canopy gear automates poorly compared with retractable gear. The outward-tilting action puts uneven strain through the operator arm, a pattern UK installers commonly report as a cause of drifted limits and premature operator wear.
- Is retractable gear more expensive than canopy gear?
- Yes, retractable gear costs more upfront because springs and tracks run down both sides of the frame rather than just the head. It is standard on the electric up-and-over bracket of £1,500–£2,500 installed and is mandatory on doubles up to around 5m wide.
- How do I tell which gear my existing door has?
- Open the door partway and look at the springs. If you see a single spring assembly across the top of the frame, it is canopy gear. If there are springs and tracks running down each side of the frame, it is retractable gear.
