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.
To read about the ways you can care for your bronze hardware, see our Bronze Care page.
All bronze darkens with age, however waxing may slow the process of oxidation.
To apply the wax, you need two 1- to 2-inch paint brushes that will be used only for cleaning bronze. Do not use brushes that have been used for other purposes as chemicals may remain in the bristles and transferred to the patina finish, may cause permanent discoloration.
Start by applying a protective circle of tape around the metal ferrules that hold the bristles in the brushes you are using. This will help prevent scratching of the surface when applying the wax and when dusting.
Wipe bronze free of-any dust and fingerprints using a clean, dry, cotton cloth. Use one of the brushes to remove dust from small crevices or hard to reach places.
Use "Renaissance'' wax, or other "microcrystalline'' waxes, because they are inert and will not yellow over time. Apply to the second brush, with three or four, back and forth, sweeping strokes. Do not dab the brush in the wax. This could cause an abundance of wax to be applied to the bronze that could actually harm the patina surface. Dab the brush on the lid of the wax can to remove any excess wax. Lightly apply a super thin coat of wax to the surface of the bronze using gentle sweeping motions. Apply more wax to the brush as described, working it down into crevices.
Caution - Using too much wax may remove previous layers of wax. It is very important not to apply too much wax or work it into the surface too vigorously. Cover the entire surface with wax and let it dry according to the directions on the container.
Separate Your Brushes
Keep your brushes separate in labeled bags, free from contaminants, for future use. Use a clean, dry, cotton cloth to gently rub, in a circular motion, the dried wax from the bronze surface until you achieve the desired sheen. To achieve a dull finish, do not rub the surface after waxing.
To achieve a better protective coating, you may want to re-apply a second coat using the same technique.
Outdoor Bronze Hardware
Outdoor bronze requires a regular maintenance program, which keeps the product surfaces clean and waxed.

Add A Dummy Handle for Double Gates?If you have a double gate, it’s an option to add a dummy handle to the outside of the inactive gate. The dummy handle gives a ‘finished’ and symmetrical look to the gates and provides a handle to pull and push the inactive gate with. For gates that will be used frequently by people who aren’t familiar with the gate: dummy handles can also cause confusion because a visitor doesn’t know which handle is operable.
Add A Gate Stop?A gate stop is needed on all gates. The stops that we have are attached to the gate and catch on the post when the gate is pushed closed. The stop maintains the proper alignment so that the latch can latch, but won’t be damaged if the gate is slammed.
Add Jar of Touch-Up PaintEach cranked band strap hinge comes with a carriage bolt, which is installed through the hinge and through the door/gate. These bolts have a silver finish. At installation, you can paint the carriage bolt’s head black with optional touch-up paint.
Add Cane Bolt?A cane bolt is needed when you have a double gate set. The cane bolt holds the inactive gate down to the ground. It can also be used to hold a gate open. Sometimes two cane bolts are used on double gates (one on each gate) so the gates can be held open (in the case of a driveway gate, for example).
BacksetThe backset is the distance from the edge of the door or gate to the centerpoint of the through-hole of the hardware. Dummy handles do not require a backset.
Deadbolts can be either “single cylinder” or “double cylinder”. Single means there is a key hole on the outside and a thumbturn on the inside. Double means there is a key hole on both sides of the deadbolt.
Door thicknessRefer to the range of acceptable thicknesses on the product description, and then choose your door’s thickness. Try to choose a thickness within 1/8” of your actual thickness.
When you need a dummy handle, you’ll need to choose which side to order. There are two options: Left and Right. Refer to the image below to determine your dummy handle.
Extension Kit for Gates up to 3.5"These latches fit gates up to 2-1/2” with the standard tongue. With the addition of an extended tongue piece, you can fit a gate or door up to 3-1/2” thick.
Gate ThicknessRefer to the range of acceptable thicknesses on the product description, and then choose your gate’s thickness. Try to choose a thickness within 1/8” of your actual thickness.
HingeA number of hinge options are available. Butt hinges work on gates that are ~6 feet high and 42” wide. A thicker gate can use a bigger butt hinge than a thinner gate. If the gate or door is wider than 48”, you should choose a strap hinge.
Interior Door FunctionWhen you need a dummy handle, you’ll need to choose which side to order. There are two options: Left and Right. Refer to the image below to determine your dummy handle.
- Passage Function: Passage or Hall and Closet Lever Handles are used on doors that do not require a locking mechanism. Halls, closets, pantry or laundry doors will generally use a passage leverset. Passage levers do not have a locking mechanism.
- Privacy Function: Privacy Hardware are most often used on Bedrooms, Baths or Office doors where a lock for privacy while occupied is desired, but a keyed lock is not really necessary. Emtek privacy levers have a push button on the rosette or backplate as shown to the left to activate the lock. On the outside, there is a pin hole for emergency unlocking. Some levers will have a pin hole inside a circular piece, some just have a small pinhole.
- Dummy Function: Emtek Double Dummy Door Knobs are sold in pairs. Dummy knobs do not have a latch or mechanism of any kind. These door knobs are surface mounted to a door that has not been bored (large hole cut out). Dummy knobs are generally used on double doors that us a ball catch at the top to keep them closed so a latch is not required. They are also commonly found on the inactive side of a french door - a single dummy mounted on either side of the inactive door.
Key All Deadbolts Alike?If you’re ordering two or more deadbolts, you have the option to use the same key for both, so that you don’t have to use separate keys. If you’re ordering one deadbolt choose “Single Lock or Not Keyed Alike.”
Mortise Lock Type
Rosette StyleThe rosette is the plate portion of your hardware. Choose the rosette that works best for the style you desire.
Screw Shape & LengthHex head screws are made of stainless steel and finished dark to coordinate with the hardware. Square head screws are made of a rust-resistant material (not stainless) and finished dark to coordinate with the hardware. If you’re in a coastal area, choosing the hex head fasteners is the best choice.
Standing in Front of the Gate, Which Way Does It Swing?This gate latch is handed one direction or the other. For single gates, you can answer the handing questions from either side of the gate as long you answer both questions standing in the same position. For double gates: answer the handing question for the active gate (the one that will have the latch installed).
Standing in the same position, what side is the gate hinged on?This gate latch is handed one direction or the other.
