Finally, one of the more technical parts of cabinet hardware are the ball-bearing slides or tracks and latches that are used to open and close drawers and cabinets. Sliding tracks are what allow drawers to open and close smoothly, and using drawer slides that have soft-close ball bearings allow them to close slowly so that they don’t make much noise or rattle everything inside. Drawer slides are available in side-mount, center-mount, and undermount versions, depending on the amount of space you have between the drawer and the cabinet opening. 
Prior to making the purchase of your new cabinet hardware, take some careful measurements of the existing hardware. Write down sizes, as well as the spacing of the screws. This should eliminate the need to drill new holes. Accurate measurements are essential to avoid additional work or the need to return and exchange your hardware purchase. In fact, it is a good idea to bring some of your old hardware with you for size comparison purposes, unless you are shopping online for your hardware. In that case, simply have the hardware next to you.

Cabinet hardware is composed a variety of materials -- most of which are metal alloys. Brass hardware typically has a lacquer or plating applied to its surface that makes it very durable in a kitchen. It is antimicrobial and helps to reduce the spread of germs. Bronze hardware is also antimicrobial, offers a substantial look and feel, and works well for cabinets made of thicker woods. Stainless steel is another option because it is so durable. Pewter and nickel are popular choices, too. Or, you can choose knobs made from glass or crystal for a vintage look. 
Let’s talk first about metals. As a general rule, I like to keep the different metals in a kitchen to no more than two. If you have stainless steel appliances, that counts as one metal. So that leaves one other metal you can bring into a kitchen. If you’ve got brass light fixtures, that’s your one other metal. Your new hardware should be nickel or brass.
