The STERLING 55wj-6 is an outside 90-degree corner fitting for the Kom-pak hydronic baseboard heating system. It provides a clean, finished transition at exterior wall corners, maintaining the continuous enclosure profile of the baseboard run. The fitting is painted classic white and is designed to integrate with the Kom-pak line's low-profile, slim enclosure. Plumbers and HVAC technicians install this component as part of a complete hydronic baseboard system, typically in residential settings where wall space is limited and a neat, uninterrupted installation is required.
The 55wj-6 corner fitting is used in residential hydronic heating installations where baseboard enclosures must navigate outside wall corners. It pairs with Kom-pak baseboard sections and accessories to form a complete, structurally consistent enclosure. The Kom-pak system is suited for residential applications including single-family homes, condominiums, and multi-unit residential buildings where low-height baseboard heating is preferred.
Designed for use with the STERLING Kom-pak hydronic baseboard heating system. Intended as a matching enclosure component for Kom-pak baseboard sections available in 2-foot through 8-foot lengths.
Installation is typically performed by a licensed plumber or hydronic heating technician as part of a baseboard heating enclosure assembly. Before beginning any work, shut off the hydronic system and allow it to depressurize and cool completely. Corner fittings should be positioned and secured before connecting adjacent baseboard sections to ensure proper alignment of the enclosure. Follow local mechanical codes and manufacturer assembly instructions for the complete Kom-pak system.
