Halero 78x40 Black Underfelt Carpet – Durable Vehicle Interior Liner

Meet Halero’s 78" x 40" Black Underfelt Carpet, a durable, unbacked interior liner designed to fit a wide range of vehicles and setups. With a total area of 21.12 square feet, this carpet provides a robust base for speakers, sub boxes, trunk spaces, and more. The material is a nonwoven fabric made from 100% polyester fiber, built to withstand heavy use without easily falling apart. Since it ships folded rather than rolled, you can lay it flat for a few hours or use a light steam iron to remove creases for a clean installation.

Versatile by design, this underfelt is suitable for cars, trucks, RVs, boats, and marine applications. It can be cut to your exact measurements, making it easy to customize to your cargo areas, speaker enclosures, or interior panels. The black interior color provides a sleek look that blends with most interiors while offering practical protection against wear and tear.
