Details Details Double Straps with Central Eye (8312) Our Double Strap Hinges with Central Eye are incredibly robust and durable! They combine heavy duty construction and strength with easy adjustment. They are ideal for use on heavy gates such as rail gates, driveway entrance gates, dumpster enclosure gates, agricultural gates and the traditional English ‘Five Bar Gate’. Double Straps not only hang the gate, they strengthen and support the gate.
