OTR Microwave Filler Options


Our Over-the-Range Microwave Filler Kits are used to fill gaps on each side of an over-the-range microwave, of which the distance between the adjacent cabinets exceeds the width of the new microwave. These filler kits are available in standard and custom sizes.


Our Over-the-Range Microwave Filler Kits are largely constructed from 22-Gauge 304 Stainless-Steel; however, we can also have these fillers powder coated in black or white finishes, using paint-grade steel. These fillers are fabricated as a channel that is bent into an L-shape form, meaning the fillers are finished on the front and bottom faces. Installation will require anchoring the fillers to the left and right-side cabinets with provided screws.

A complete line of kits is available to fit your personal requirements whether your project is a new home, a complete remodel, or simply an appliance change out.

    I just had the opportunity to install our new trim kit for the micro-hood in our renovated kitchen, and it looks fabulous! Thank you for your professional service, and for a great product at a good price.

    Some months ago, we ordered some microwave fillers for our new microwave from you. We are very pleased with the fillers. As you may recall, one of the original filler pieces mailed to us had a punch like dent in it when it arrived. You immediately made this right, going so far as to send the replacement trim pieces to us by overnight mail, which was not at all expected and very much appreciated. We have been very pleased with the service received from Micro-Trim and the final product itself.

    We just finished the install of our new OTR microwave. Your standard stainless steel kit was used to install a 30” Microwave in a 36” opening. Easy to install. Filler kit fit perfectly with new GE JVM6175SK2SS microwave oven.
