UPVCSTORE Caldwell Bi-fold Door Hinge

These high-quality PAS 24 compliant hinges are part of the Caldwell range of folding door hardware. They’re used to form a joint between two door panels or between the hinged door and frame to achieve a smooth, superior folding operation. And once the doors are shut, they’ll ensure a flush, firm, secure seal to keep out moisture or drafts and deter burglars.
