What about ventilation?

Proper airflow is critical for the longevity and safety of your microwave. Our custom trim kits are engineered with a built-in ventilation system that often exceeds standard OEM kits.

Integrated Airflow Design
Dual-Slot System: Each kit includes precision-engineered ventilation slots running the full length of both the top and bottom edges.
Generous Open Area: These 3/8-inch deep openings provide over 15 square inches of open ventilation area per kit.
Superior Performance: This design allows air to move freely in and out of the cabinet space, meeting or exceeding the ventilation found in most manufacturer (OEM) trim kits.
Seamless Protection
While the ventilation is highly effective, the slots are discreetly integrated into the design. You get the peace of mind that your appliance is breathing properly without sacrificing the sleek, "built-in" look of your kitchen.

What’s in the box?

Each kit includes:

Hardware to raise and center the microwave
Brackets to keep everything secure during use
A decorative front trim piece to cover gaps and create a clean, built-in look
Everything you need for a solid, seamless install is included.

Shipping and returns

Once your measurements are confirmed, we build and ship your kit quickly. Shipping and returns are always free within the contiguous U.S. If anything’s off, we’ll fix it or refund you. 100% satisfaction guaranteed.

Quality stainless steel construction and fast delivery (often under 2 weeks) impressed buyers. Some found the price high but worthwhile, while a few noted challenges with tape adhesion during installation.

Great communcation through the process. I like the idea of answering my questions via U-Tube (Example, how to install or does it come with ventilation) I have a nice home, it maintained the level I was looking for.

Sleek design with a built-in look. Great finish for our kitchen refurb.

The kit looks and fits great. Saved money compared to other options on the market, and the company was fantastic to work with. Very happy with everything

I was skeptical ordering something so customized online, but everything was flawless. Several helpful videos and quick replies to email questions assured me my measurements were correct. The product arrived with additional video links for installation. Installation took two of us (with common sense but minimal carpentry skills) about an hour to complete. The finished product looks great, fits perfectly, and was by far the most economical solution to replacing a broken microwave within an existing cutout.

Love the look with vents on top/bottom out of view; love the fit. Much better than the OEM stainless "finish" plastic that had vents on the sides that looked weird and rather shabby. Following Appliance Trim Kit's measuring instructions was straightforward; the short videos for each measurement were helpful. Similarly for installation. From ordering to receiving the kit was under 2 weeks. Worth the extra cost (vs OEM) for actual stainless. We're very satisfied.

Great product. Great people to work with.

Although the profile of our custom microwave trim kit isn't flush with our oven, it's a better fit than the oven manufacturer's trim kit. It's better in price than the manufacturer's and the thickness of each side (top, bottom, left, right) look more even and seamless. (Oven manufacturer's kit is too thick at top and bottom, for our intended cabinet allowances).
We're quite pleased.

Our microwave trim kit trim kit turned out great. We are very happy with the way it looks in our kitchen. My husband installed it with the help of the videos that were provided and email support answering our questions while installing. I would highly recommend this company. The product and support for installing were excellent.

So happy I found this company! We remodel a kitchen and the designer made a error in measuring for the under counter microwave. Panic struck and the search began! From the inquiry to production ATK was so helpful and responsive to every question and concern. Sample color was received within 4 days of request and complete trim kit was received 3weeks after ordering. Easy process for start to finish. Could not be more thankful for finding this company!

Thank you! Everything went GREAT. Worked as I had hoped. Replaced a door microwave with drawer microwave. The old door microwave had a plastic trim piece, which was “OKAY”. This is a little expensive but it is QUALITY built and looks GREAT. My wife really liked seeing the upper vents as he old plastic one did not have any.

The microwave trim kit looks great, it really finishes out our kitchen. I am pleased and would purchase again. The whole experience was a delight 😊

We needed a new microwave and didn’t think about how it would fit in the old cabinet.
The trim kit fit perfectly, easy to install with video instructions.
I would buy again if needed.

Quality product and great customer service. My install was very tight and required a height adjustment to the original risers provided with the kit. One contact with customer support and new risers were on their way at no additional charge. Install looks great, highly recommended!

Great product and installation videos. This step by step instructions and video process is excellent. We couldn’t be happier. I’ll definitely be a return customer. Not a cheap product but I’m a firm believer in “you get what you pay for”.

I had an absolutely outstanding experience with Appliance Trim Kits ATK. From the very beginning, they took the time to walk me through every measurement and design detail, making sure everything would fit perfectly and look seamless. That level of patience and expertise is rare, and it made the entire process feel effortless.

When the final product arrived, it was flawless, truly precision‑engineered. You can tell immediately that this isn’t a company that creates something once and calls it done. After watching their demonstration videos, it’s clear that they are constantly refining, improving, and engineering smarter solutions. The evolution of their designs shows a commitment to excellence that hasn’t slowed down for a moment.

And the delivery speed was unbelievable. From the moment I placed the order to the moment it arrived at my door, the turnaround time was incredibly fast. It’s obvious they’ve built a system that respects the customer’s time as much as the quality of the product.

Thank you, Appliance Trim Kits ATK, for the exceptional service, the thoughtful guidance, the engineering brilliance, and the lightning‑fast delivery.

Frequently Asked Questions

Do I need to send measurements before I order?

Nope — order first, measure later. Once your order is placed, we'll email you a simple measurement form with instructions and a short video. Submit your dimensions and a few photos, and we confirm everything before fabricating. You won't be locked into measurements you're unsure about.

How accurate do my measurements need to be?

Very accurate — to 1/16 of an inch is ideal. That's what makes the fit custom. Don't worry, our measurement guide walks you through exactly what to measure and how.

How long does it take to receive my kit?

Lead time is approximately 2 weeks after your measurements are confirmed. We build each kit to order, so we don't keep pre-cut inventory. Once shipped, your kit travels via USPS Priority Mail. You'll receive a tracking number as soon as it's on its way. Free shipping to anywhere in the contiguous USA.

What if my kit doesn't fit?

In the unlikely event that this happens, we will make it right. Every kit is backed by our 100% satisfaction guarantee. If the fit isn't perfect, we'll remake your kit at no charge or issue a full refund. No runaround, no restocking fees. Just email us and we’ll take care of it.

Is any special tool or skill required to install?

None. You'll need a screwdriver and a tape measure — that's it. The 4-piece flat-pack assembles quickly and mounts using the included magnetic mounting system. Step-by-step install videos are included with every kit. Most customers complete installation in 30 minutes or less, even with no prior experience.

Are your kits metal or plastic?

Our kits are made from high-quality metal components for durability and longevity.
