As with most quality hardware designed for use with aluminum, vinyl, wrought iron, and ornamental steel gates, these hinges connect to both the gate and the hinge post on two adjacent sides of the posts/ verticals for added strength. These hinges are designed for use on residential and commercial gates with 2" and larger gate profiles. Hinges are equipped with adjustable pins to fit most openings. Hinges are constructed from stainless steel and include a powder coat finish for a long-lasting performance.
