Strainer Specialists

We are Kochek specialists. We deal with various threads and finishes daily. Our goal is to help you order the correct strainer the first time. However, many strainers are made to order. Unfortunately, they are not subject to cancelation or return once your order has been submitted. Please give us a call before ordering if you are uncertain of your thread types, finishes, sizes, colors, or have any other questions.
