The STERLING 55wj-9a is a 2.5-inch Kompak baseboard trim strip finished in classic white, designed for use with Sterling hydronic baseboard heating systems. This trim strip serves as the enclosure component that covers and protects the heating element assembly while contributing to the system's clean, low-profile appearance. The radius-formed end covers and smooth enclosure design give the unit a sleek, flowing silhouette suited to residential interiors. Heavy-gauge brackets snap into place without sheet metal screws, reducing installation time. The part is installed by licensed plumbing and HVAC professionals during new hydronic baseboard installations or trim replacement service calls.

Telescoping fill-in sections eliminate the need for field cutting, reducing waste and labor. Available section lengths include 2, 3, 4, 5, 6, 7, and 8 foot units, with splice plates provided with 8-foot, 6-foot, and 5-foot lengths.
