J-Trim – 1/2" x 12' – White

This white 1/2" × 12' J-trim is designed to provide a clean finishing edge around exterior siding panels. Used as a border piece, it neatly frames ends, openings, and transition points while helping protect exposed areas. The 12' length reduces the number of joints required, and the narrow 1/2" profile fits well with common residential siding systems. Lightweight and easy to handle, it integrates smoothly into projects that require a discreet and cohesive exterior finish. A practical option for completing new siding layouts or replacing worn trim sections.
