Trim kits and gap fillers finish the opening around a built-in appliance so it sits flush with the cabinets. This collection holds the kits Summit makes for its wall ovens, built-in microwaves, speed ovens and ranges.
Kits are listed by width and finish, including stainless steel and matte black, with custom-size options for openings that do not match a standard width.
Why Trim and Filler Kits Matter
- Finished look: A trim kit closes the gap between the appliance and the cabinet cutout.
- Fit wider openings: Filler kits let a 24 inch oven sit in a 27, 30 or 36 inch opening.
- Keeps debris out: Stove gap fillers cover the space between a range and the counter.
