OAKMONT, PA (April 7, 2026) – Chelsea Building Products, manufacturer of Everlast® advanced composite siding, is adding a new accessory to its collection of high-performance trim products with the Everlast® Inside Corner Post. The one-piece trim is designed to simplify installation for contractors while providing a refined finished appearance for homeowners.
Built from the same high-performance formulation as Everlast siding, the Inside Corner Post reduces labor by eliminating the need to piece together two separate J-trims. It features a 2-¼" reveal and is offered in 10' lengths. Each post is finished with Everlast siding’s signature CedarTouch® finish and available in 15 timeless colors.
“The introduction of the Inside Corner Post is in direct response to customer demand for it,” said Gary Hartman, vice president of sales and marketing at Chelsea Building Products. “This new accessory complements the Everlast siding trim package, giving contractors and homeowners a full suite of options to create polished, professional exteriors.”
For installation versatility, the Inside Corner Post offers multiple fastening options, including using the built-in nailing hem or directly into the trim body with color-matched Everlast Cortex<® hidden fasteners or standard finishing nails. Like all Everlast siding trim profiles, the Inside Corner Post features a 100% acrylic cap stock, ensuring long-lasting color retention and enhanced impact resistance. Everlast siding products are dimensionally stable and engineered for minimal expansion and contraction.
The new trim is compatible with all Everlast siding profiles: 4-½" and 7" horizontal lap siding, and the 11" vertical board and batten profile.
The Inside Corner Post is backed by a transferable, best-in-category limited lifetime warranty.
