Sterling 55wq-5 Inside Corner 90 Degree Baseboard White

Product Description

The STERLING 55wq-5 is an inside corner fitting designed for use with the Sterling Senior hydronic baseboard heating system. This 90-degree corner piece allows the baseboard enclosure to transition cleanly at interior wall corners, maintaining a continuous, finished appearance throughout the installation. Painted in a classic white finish, it is suited for residential and light commercial environments where a clean, professional look is required. The Senior series is a hi-output hydronic baseboard line built for larger residential and light commercial applications where standard-output baseboards may fall short.

This inside corner fitting is used wherever a Sterling Senior hydronic baseboard run meets a 90-degree interior corner. It integrates with the Senior enclosure system, which features smooth radius-formed end covers and a flowing enclosure design. The fitting is compatible with the Senior series baseboard lengths available in 2-foot through 8-foot sections, including telescoping fill-in sections. Installations are typically found in residential living spaces, commercial lobbies, and other areas where wall space is limited but heating output requirements are high.

Installation Notes

Installation of hydronic baseboard fittings and enclosures is typically performed by a licensed plumber or hydronic heating technician. Before beginning any work, shut off and depressurize the hydronic system and allow it to cool completely. Ensure all enclosure components are aligned and seated properly before securing to the wall. Local mechanical codes and manufacturer instructions should be followed for all hydronic system connections and enclosure assembly.
