Sterling 55wq-3al Senior Baseboard Left End Cap White

Product Description

The STERLING 55wq-3al is a left-hand end cap for the Senior (Hi-Output) hydronic baseboard heating system, finished in white. This trim component provides a clean, finished termination at the left end of a Senior series baseboard enclosure. It is designed to match the radius-formed, smooth enclosure lines of the Senior baseboard line. The end cap contributes to the structural integrity of the enclosure while maintaining the series aesthetic. Installation is typically performed by licensed plumbers or HVAC technicians working on hydronic heating systems in residential or light commercial settings.

The Senior series is engineered for large residential and light commercial hydronic heating applications where higher output is required. This end cap is used wherever a Senior series baseboard run terminates on the left side, completing the enclosure without requiring field fabrication or cutting. The white finish is designed to complement standard interior wall colors and decor. This component works as part of a complete baseboard assembly that includes heating elements, brackets, and enclosure sections.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians servicing hydronic heating systems. Shut down the boiler and allow the system to cool before working on baseboard components. This end cap is a trim and enclosure component and does not require connection to the hydronic circuit, but surrounding piping and heating elements should be fully seated and secured before attaching end covers. Refer to local mechanical codes for applicable requirements.
