Mack Door Knob Set

Rocky Mountain Hardware finishes are considered living finishes. They are designed to age and change in color over time, gaining character as they do. Typically, these finishes will lighten where frequently touched and darken where they are not. In exterior conditions, they may even take on a beautiful turquoise hue. Even in harsh exterior environments, the bronze material will never rust or deteriorate. Use of a high-quality, clear paste wax can be used to help preserve the original finish if desired.

Clean with a soft, non-abrasive cloth dampened with warm water. Mild diluted dish soap may be used if needed. Dry thoroughly. Do not use cleaning chemicals or disinfectants as they may damage the finish.

Residential Warranty:

Rocky Mountain Hardware stands behind all of our bronze products with a lifetime guarantee on material and workmanship. In addition, the internal mechanisms, including all locks, latches, etc., are guaranteed for 50 years from the date of sale to the original user. Rocky Mountain Hardware will repair or replace the defective product or parts that fall within these guidelines. When necessary, a proof of purchase dated within the warranty period may be required. The patina finish applied to our bronze products is known as a “living finish” which means it will change with time, touch, climate, etc. Because each product will be exposed to a varying set of conditions, we do not warranty the finish of our products.

Commercial Warranty:

We offer a 20 year warranty on the bronze products and a 5 year warranty on the internal mechanisms. We do not warranty patina finish which is a living finish and will wear dependent on use and location.

Rocky Mountain Hardware will not assume liability for any labor charges regarding the removal or reinstallation of the products; nor will we cover any freight, postage, or handling expense related to the product. Damages caused by accident, misuse, abuse, or improper installation are not covered by this warranty.
