The Spring inside a manual door is a component that prevents dangerous movement of the door, in normal operation this single component makes lifting a door that’s potentially heavier than the operator easy to do with little effort, however, if it breaks then the door becomes very heavy can easily cause injury and therefore there are very few situations where an inertia brake should not be used as part of the system,

We hold stock of a wide range of springs and when used in combination can correctly balance most doors to allow very easy and controlled movement of the door, for the situations where this is not possible we have access to a fast turnaround for bespoke springs.
