Designed for surface mounting. Each set contains 2 left-hand hinges, 2 right-hand hinges, and 2 sets of fasteners -- enough shutter hardware to complete one window.
Note: This product is cast iron and does not have a finish on it. You should use a Cold Galvanizing Compound (Rust-Oleum or another brand) to coat the raw cast iron before priming and painting the hinges. There is no warranty on this product against rusting and we do not warranty your paint finish under any circumstance.
