Hi,

Does anyone know the rough price of a sliding garage door? Say a 3m by 3m?

Do you mean the type that slides to the inside of the garage.

The gear is made by henderson it is called ROUND the CORNER

The model for residential doors is the Tangent 290

Go to www.pchenderson.co.uk then sliding door gear/industrial/round the
corner

As to price will depend on opening size and how many door leafs,but it will
not be cheap,have replace the gear on a few occasions and that was always
expensive.
