Arched Plate Mortise Entry Lockset
with your choice of knob, lever, or ring

This bronze mortise entry set is the epitome of architectural front door hardware. With a rustic texture and a dark bronze living patina finish,  these locks are suitable for the very finest homes and their exterior doors. The dark bronze finish is reminiscent of an oil rubbed bronze. 

A combination of decorative door hardware and functional entry lock set, the arched plates add an elegant dimension to the aesthetic. Choose from eight different knobs, levers, or a ring handle to complete the set. The mortise lock has a Schlage C Keyway.

The backplates are available in two sizes, either 8" high or 11" high. Once the bolt is unlocked, the hardware is operated with the bronze lever, bronze knob, or bronze ring of your choice.

Hardware Tips

About This Bronze Hardware:

This bronze hardware contains 90% copper and 10% tin. When it first leaves the mold, the hardware is copper-penny colored. Next, the pieces are patina’d dark bronze. Finally, the hardware has an exterior-grade dark bronze-colored wax applied to it that adds to its weather- and wear-resistance. Bronze ages gracefully and may change in appearance due to varying environmental conditions. The wax helps maintain the color of the hardware for the long term under most conditions. On items like gate latches and door handles where your hand comes in contact with the material regularly: we’ve seen over time that the oils on your skin will slowly wear down the wax where the skin contacts the metal. On all other items where skin doesn’t come in contact with the hardware, you should see dark bronze coloration for the long term.

How does this hardware hold up to the elements? When submitted to a salt-water chamber test, this hardware began to patina at the 16-hour-mark, versus 10-hours for other name-brand, high end bronze products. A client recently wrote that this hardware installed on an waterfront boathouse two years ago looks slightly darker and shinier than the original, but looks otherwise exceptional.

The bottom line is: this hardware is the perfect choice for oceanfront, waterfront, and coastal installations.

Coastal Bronze warrants all flat goods (non-locking) to be free of defects in material and craftsmanship for five years from the original invoice date. Coastal Bronze warrants all locking goods, including locks, latches and deadbolts, to be free of defects in material and craftsmanship for 1 year from the original invoice date. In areas of high humidity or proximity to ocean, warranty is 6 months. Coastal Bronze adds a patina to all products to simulate aged bronze. Finishes will develop a wear highlight and may change color based on environment. This is not considered a defect, but part of the natural beauty of aged bronze.
