The STERLING 55wj-4l is a left-hand end cap designed for use with the Sterling Kompak hydronic baseboard heating system. Finished in classic white, this end cap measures 6 inches and provides a clean, finished termination at the left end of a Kompak baseboard enclosure. The radius-formed profile blends with the enclosure's flowing lines for a cohesive appearance. It is installed by residential HVAC technicians and plumbers working on hydronic heating systems where a polished finish at baseboard terminations is required. The cap contributes to the structural integrity of the enclosure assembly.
This end cap is suited for residential hydronic baseboard heating installations where wall space is limited and a low-profile enclosure is needed. The Kompak line is designed for standard residential applications. The 6-inch size accommodates typical Kompak enclosure depths. Installers fitting or replacing damaged end covers on existing Kompak baseboard runs will find this a direct-fit replacement component.
Designed for use with the Sterling Kompak hydronic baseboard heating system. Compatible with Kompak enclosures in residential applications. Consult Sterling documentation to confirm fitment with specific enclosure lengths and configurations.
Installation is performed by licensed plumbers or HVAC technicians servicing hydronic heating systems. Before replacing or installing end caps, shut down the boiler and allow the system to cool to relieve pressure and prevent burns from hot water or steam. Standard hand tools are typically sufficient for end cap installation on baseboard enclosures. Ensure the enclosure is properly aligned and seated before securing the end cap to maintain a flush, finished appearance.
