These are PERFECT for replacing old knobs/handles without having to worry about finding the exact same size (just make sure the handle length you choose is slightly longer than the width of the spacing of any pre-existing holes). The adjustable feature allows you to fit them for any size and they were very easy to install. Each handle comes with 2 set of screws at 2 different lengths to insure it works for your cabinet depth. They also provide a handy tool to secure the nuts onto each screw. These are all the PRACTICAL features that make these handles great, which I rarely care about, as I am all about the design and aesthetic. These handles are sleek and modern but can also work well for a rustic design. Once installed, they are strong and easy to grip. I'm ordering MORE to put on our bar cabinets now to match our kitchen!
