Roller Blinds Information

Spring Mechanism

A spring mechanism inserted into an aluminum tube, operated by cord control on endless loop for precise positioning. It is this that pulls the blind up and down. Maximum drop determined by weight of cloth (mechanism sometimes referred to as a sidewinder).

Metal Spring Roller

The blind is usually pulled down by a centre cord. This allows the blind to stop wherever you would like it to as a result of this mechanism. Many find the spring operated roller blinds difficult to operate and so many blinds companies do not offer it as a standard option. We can supply this type of blind. If you wish to purchase a blind with this system, you can submit your order online but please add the request in the delivery instruction section or contact us us beforehand and we will ensure that you receive the blinds you would like.
