Sterling 55wj-5 Hydronic Baseboard Inside Corner White

Product Description

The STERLING 55wj-5 is an inside corner fitting designed for use with the Kom-pak hydronic baseboard heating system. This 90-degree inside corner piece allows installers to route baseboard enclosures cleanly around interior wall corners without cutting or fabricating custom transitions. Finished in classic white, it integrates with the Kom-pak enclosure system's sleek, radius-formed lines to maintain a consistent appearance throughout the installation. Licensed HVAC technicians and plumbers install this component as part of complete hydronic baseboard heating systems in residential settings where low-profile, wall-hugging baseboard runs are required.

This inside corner fitting is used in residential hydronic heating installations where baseboard runs must navigate 90-degree interior corners. The Kom-pak series is designed for low-height applications where wall space is limited, making this corner piece appropriate for rooms with furniture, cabinetry, or architectural features that restrict standard baseboard depth. It is compatible with the Sterling Kom-pak baseboard enclosure system and is typically installed as part of a complete perimeter baseboard heating layout.

Installation Notes

This corner fitting is installed by licensed plumbers or HVAC technicians as part of a hydronic baseboard heating system. Shut down the boiler and allow the system to depressurize and cool before modifying any enclosure components or connecting to piping. Verify that the baseboard enclosure run is properly supported and that heating elements have adequate clearance to expand during operation. Follow local mechanical codes and the manufacturer's enclosure assembly sequence when fitting corner pieces into the overall baseboard run.
