The STERLING 55wj-4r is a right-hand end cap designed for use with the Kompak hydronic baseboard heating system. Finished in classic white, this 6-inch end cap provides a clean, finished termination at the right-hand end of a Kompak baseboard enclosure. The radius-formed profile blends with the unit's smooth, flowing enclosure lines for a cohesive appearance on the finished wall. Licensed HVAC and plumbing contractors install this component as part of hydronic baseboard heating installations in residential settings where a professional, low-profile finish is required at section endpoints.
This end cap is suited for residential hydronic baseboard heating applications where the Kompak series enclosure is used. It is typically installed in rooms where wall space is limited and a slim, low-height baseboard profile is specified. The white finish complements standard interior trim and drywall. It is compatible with Kompak series baseboard sections and is used to cap the right-hand terminus of a run, providing structural closure and a finished aesthetic consistent with the rest of the baseboard system.
Designed for use with the STERLING Kompak series hydronic baseboard heating system as a right-hand enclosure end cap.
Installation of hydronic baseboard components should be performed by a licensed HVAC or plumbing technician. Shut down the hydronic heating system and allow the baseboard elements to cool fully before handling any enclosure parts. End caps are typically snapped or fastened into place at the terminal end of the baseboard run following element and bracket installation. Follow all applicable local mechanical and plumbing codes during service or installation.
