How to measure and order?

Getting a pro-built, seamless look for your microwave is a simple three-step process. We handle the technical details so you don't have to worry about a "mis-fit."1.

Whether that requires replacement parts or a full refund, we guarantee a stress-free experience from start to finish.

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.

Frequently Asked Questions

What makes the Essential kit different from the Premium kit?

The Essential ships as a 4-piece flat-pack you assemble on site, features mitered corner seams, and has visible screws on the top and bottom panels. The Premium ships fully assembled as a single piece with no seams and no visible hardware. Both are custom-fabricated from real stainless steel to your exact measurements. The Essential is the smart choice if you want a clean, custom fit at a lower price point.

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.

Can I add risers to my Essential kit?

Yes. Risers are an optional add-on for the Essential kit at +$40. They center and raise your microwave within the opening for a more balanced, built-in look. If you don’t want to build your own, our custom risers are worth considering. You can add them at checkout.

What finish options are available for the Essential kit?

The Essential Trim Kit is available in brushed stainless steel. If you need matte black, satin white, or black stainless, those finishes are available on our Premium Trim Kit. Both kits are fabricated from the same high-quality stainless steel — the Premium just offers more finish variety and a fully assembled, seamless construction.

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.

Where is the Essential Trim Kit made?

Right here in Tulsa, Oklahoma. Every kit is fabricated in our USA shop by our own team — not outsourced, not mass-produced overseas. When you order an Essential kit, you're getting a piece built specifically for your kitchen, by people who take that seriously.
