When replacing garage springs, it is recommended to replace both springs at the same time, to ensure the spring tension and door remain balanced.
Garador Genuine DC/CM type spring is to suit DOUBLE canopy doors with two springs down either side. These doors have horizontal tracks, when the door is open it sticks out approx one third of it’s height.
You can identify that your door is a DC/CM type as the lift arms are straight – not to be confused with Garador’s double retractable doors which had a kinked arm. It is recommended that you replace a pair at the same time.
