The hinge length to be used depends on the application, 1/3 the width (or next hinge size up) of the gate or door for a normal domestic installation, with the hinge length being 1/2 the door or gate width (or nearest hinge size up) for industrial use of heavy duty domestic use.
Doors or gates over 2130mm/7ft in height will need 3 hinges per door or gate.
Unlike the Galv and standard black band and gudgeon hinges, the premium black hook and band hinges are only manufactured in four sizes 18″/450mm, 24″/600mm, 750mm/30″ and 36″/900mm.
All hinges are supplied with screws and bolts.
Unlike the normal range of E-black ironmongery, the premium range of black ironmongery is steel that has undergone galvanisation (hot dipped/hot spelter galv) that is then powder coated black.
This gives two levels of protection to the ironmongery with the powder coating adding to the already long lasting galv!
