This 30 in. gap filler kit is designed to fill the rear space behind a slide-in range, creating a clean transition between the stove and the counter. It offers three selectable widths: 1.49 inches, 2.24 inches, and 2.64 in. to match gaps of varying sizes, with a fixed 30 in. length that fits standard setups. Before purchasing, measure the gap between wall and stove to verify compatibility, and note that this kit is intended for ranges with slim back panels rather than bulky backguards. The filler uses an aluminum strip with a surface treatment to resist oxidation, moisture, and heat, and the enclosed profile helps keep dirt from collecting at the joint. The triangular shape provides stable coverage along the rear edge, and the design accommodates easy cleaning by reducing crevices where debris can collect. Installation is straightforward: it comes with clear instructions and mounting hardware, and no special tools or appliance disassembly are required. The kit stays firmly in place during daily use thanks to a combination of punch-free adhesive brackets and dedicated mounting brackets. The package includes one triangular gap strip, two punch-free self-adhesive brackets, two non-slip mounting brackets, six screws, and an installation manual. This setup helps prevent crumbs, spills, and residues from dropping into gaps between stove, counter, oven, and cooktop areas.
