The best 30-inch cooktop trim kit depends on where the gap is and how wide it measures. For a rear gap behind a slide-in range, the Eveanro stainless steel kit offers two width options, while its aluminum version has three selectable widths. For a side gap, the Gosmol silicone cover is designed to fit between a stove and counter. Jnfmiler’s adhesive stainless steel strips are a more versatile decorative option for smooth surfaces. Measure before choosing: these products are not interchangeable.

| Eveanro aluminum rear filler | Slide-in ranges needing width flexibility | 30 inches long; three selectable widths |
| Gosmol silicone gap cover | Side gaps between stove and counter | Fits 0.2- to 1-inch gaps |
| Jnfmiler stainless steel strips | Decorative coverage on smooth surfaces | Two 30-inch-long, 1.5-inch-wide strips |
Eveanro Stainless Steel Rear Filler Kit
This black stainless steel kit is best for a 30-inch slide-in range with a gap behind the appliance. It includes two silicone stove gap covers and a stainless steel filler, with listed width choices of 1 inch and 2-1/4 inches. The product description names Whirlpool, Samsung, KitchenAid, Frigidaire, GE, and most cooktop brands, and lists several replacement part numbers.
Choose this option if your measured rear gap matches one of its two widths and you want a metal finish. The limitation is fit: it is not intended for freestanding ranges with bulky backguards or granite countertops. Measure the gap and confirm the range style before buying.
Eveanro Aluminum Triangular Rear Filler
This 30-inch aluminum filler is best for buyers who need more flexibility in rear-gap width. Its triangular profile provides three selectable widths: 1.49, 2.24, and 2.64 inches. The maker lists it for slide-in ranges from Whirlpool, Samsung, KitchenAid, Frigidaire, GE, and other brands, and identifies replacement part numbers.
It is a practical choice when one of the three stated widths matches the measured space. Avoid this kit if the range is freestanding with a bulky backguard, or if the gap length is not 30 inches. The product information specifies slide-in ranges without bulky backguards.
Gosmol Silicone Side Gap Covers
Gosmol’s two-piece silicone set is best for filling a side gap between a stove and counter, rather than the rear space behind a range. Each cover is 1.5 inches wide and more than 30 inches long. The flexible material can be cut to size, and its insert tab is described as 0.8 inches long to help keep the cover in place during routine cleaning.
Choose this set if the side gap measures between 0.2 and 1 inch and the stove and counter are at the same height. It is not suitable for narrower or wider gaps, or for surfaces at different heights. Those fit limits make measuring especially important.
Jnfmiler Adhesive Stainless Steel Strips
This two-piece set is best for buyers seeking a surface-mounted decorative trim for a range, oven, microwave, or other appliance gap. Each 304 stainless steel strip is 30 inches long and 1.5 inches wide, with a brushed finish and peel-and-stick backing. The product description says to clean and prepare a smooth surface, then position and press the strip into place.
Choose it when adhesive installation and a brushed metal appearance suit the surface and gap. Unlike the rear filler kits, these are flat adhesive strips, not a shaped insert specifically described for slide-in range backs. The listed adhesion is for smooth surfaces, so do not assume it will hold on every material or texture.
Buying Guide: How To Choose A 30-Inch Cooktop Trim Kit
Where is the gap?
Identify whether the opening is behind the range or between the range and a side counter. Rear filler kits are designed for the wall-side space behind slide-in ranges. Silicone gap covers address side gaps, while flat adhesive strips can be used for surface trim in several appliance locations. Choosing by location prevents mismatched shapes and installation methods.
What should you measure?
- Measure the gap length and width, rather than relying only on the nominal 30-inch appliance size.
- For a rear filler, check that the range is a slide-in model and note whether it has a bulky backguard.
- For a silicone side cover, confirm the gap is 0.2 to 1 inch and the surfaces are level.
- For adhesive strips, check that the intended mounting surface is smooth and can accept adhesive.
Which material and installation style fits your needs?
Stainless steel and aluminum rear fillers provide shaped coverage behind a slide-in range; compare their listed width options against your measurement. Silicone is flexible and cuttable, but its stated side-gap dimensions are narrow. Adhesive stainless steel strips offer a flat, peel-and-stick approach, but they are not the same as a fitted rear filler. Match the material and mounting method to the location and surface.

No. Length alone does not confirm fit. Check the gap width, range style, backguard shape, and the product’s stated restrictions.
Can I use a rear filler on a freestanding range?

No. It is described as a side gap cover for the space between a stove and counter, with a fit range of 0.2 to 1 inch.
Can I cut these products to fit?
The Gosmol silicone cover is described as easy to cut. The supplied details do not state that the rear filler kits or Jnfmiler metal strips can be cut, so verify before altering them.
