Restrictors, stops and holders are designed to control the inward and outward opening angles of doors. Ironmongery Direct stocks; concealed door restrictors/stops, surface mounted friction restraining stays, and door check chains on plates, ideal for garages, workshops or agricultural doors. Our concealed door restrictors/holders and automatic door holders are ideal for summer doors where they are held firmly in position until they are pulled shut. Door and casement friction restrictor stays are a strong but simple design, ideally for windy locations where doors are secured into place so that they cannot be forcibly thrown open when the wind catches them. As well as this we offer a friction mortice restraining stay which is primarily morticed into place on the top edge of the door leaf, but also can be used in timber, PVCu and aluminium window applications.
