Sterling 55wj-9c Kompak Baseboard Trim Strip White

Product Description

The STERLING 55wj-9c is a 4.25-inch Kompak baseboard trim strip finished in white, designed for hydronic heating systems in residential and light commercial construction. This low-profile enclosure provides a clean, finished appearance while housing the heating element and fin assembly that delivers convective heat output. The slim silhouette keeps the unit's footprint minimal, making it well suited for rooms where wall space is at a premium. Installation is handled by licensed HVAC technicians or plumbers working on hydronic baseboard systems. The enclosure is built with heavy-gauge components engineered for structural rigidity and freedom from warping over the life of the system.

The 55wj-9c trim strip is used in residential hydronic baseboard heating systems where a low-height, aesthetically integrated enclosure is required. It is part of the Sterling Kompak product line, which targets standard residential applications. The matching Senior (Hi-Output) line addresses larger residential and light commercial loads. Available lengths include 2, 3, 4, 5, 6, 7, and 8 feet, with telescoping sections available in 14-foot lengths for continuous runs. Splice plates ship with the 5-foot, 6-foot, and 8-foot configurations to simplify joining sections without additional hardware.

Installation Notes

Installation is performed by licensed HVAC technicians or plumbers trained in hydronic heating systems. Shut down the boiler and relieve system pressure before disconnecting or repositioning any baseboard element. Verify that fin assemblies and heating elements are seated correctly before securing the enclosure. Work should conform to applicable local mechanical codes and the IFGC where relevant.
