The STERLING HVAC HTR-55RA-ECR-03 is a solid right-hand end cap designed for hydronic baseboard heating systems. Cast from steel with a high-grade enamel finish, this end cap measures 3 inches in width and provides a clean, professional termination at the right-side ends of baseboard enclosures. It is a finish component installed by HVAC technicians and plumbers during hydronic baseboard installation or service. The right-hand orientation ensures correct fitment when terminating runs at doorways, wall ends, or corners where the baseboard terminates on the right side.
This end cap is suited for residential and light commercial hydronic baseboard heating applications. It is part of the Sterling Baseboard product line and is used to close off the exposed right-hand end of the baseboard enclosure, protecting internal components and delivering a finished appearance. Installers typically use this component during new construction or retrofit projects where a proper enclosure termination is required.
Designed as an OEM-style replacement end cap for the Sterling Baseboard hydronic heating enclosure line, right-hand termination applications.
Installation should be performed by a licensed HVAC technician or plumber familiar with hydronic baseboard systems. Shut down the boiler and allow the system to cool before servicing any baseboard enclosure components. Verify that the right-hand orientation matches the intended termination side before securing the end cap to the enclosure. Follow all applicable local mechanical codes during installation.
