High quality hinges between door leafs provide a quality folding operation, whilst also folding to create a flush, secure seal against external conditions .
Rollers
Supporting vents up to 100kg, our rollers are made with chrome brass wheels with high quality bearings to facilitate a continued smooth sliding operation. Rollers from Caldwell are also supplied with an aluminium hinge bespoke to the door’s profile making for a fit perfectly matched to your door.
Additionally, Caldwell are also able to supply single rollers which allows vents to rest adjacent to the door vents or frame.
