Solid bronze thumb latch for "back-to-back" gate or door installations. A "back-to-back" installation is one in which each thumb latch is installed exactly opposite each other, one on the inside of the gate and one on the outside of the gate. Our solid bronze hardware is great for use in coastal areas or anywhere a rustic old world design is desired. Bronze is an old world material that does not deteriorate in coastal or other regions. Bronze is a "living" finish. It may change color over time. The use of a gate stop with this product is strongly recommended to protect the drop bar. A gate that slams in a strong wind can damage a bronze drop bar. The installation of a gate stop will protect the drop bar. This latch is made up of 3 components; an inside thumb latch, an outside thumb latch and a drop bar (latching mechanism). Each thumb latch measures 8-5/8" tall by approximately 1-7/8" wide at the widest point. The drop bar measures approximately 8" wide by 4" tall at the tallest point There are three different models available depending on your gate thickness. Be sure to measure your gate before selecting a size. Sold by the Set. One Set will latch one door.
