This 135-degree corner cover provides a finished appearance at projecting wall corners, bridging the gap between adjacent baseboard sections with a clean, factory-matched look. It is compatible with both 90-degree and 135-degree corner configurations, offering flexibility across a range of wall layouts. Designed for deluxe residential and light commercial applications, this component is typically installed by HVAC technicians or plumbers completing hot water or steam baseboard heating system trim-out work.
This outside corner is used wherever Multi/Pak 88 baseboard runs meet a projecting wall corner in residential or light commercial settings. It is suited for installation in rooms where wall space is limited and a clean finish is required around heating elements. The piece accommodates gaps of up to 1 inch on each wall, making it practical in real-world construction where walls are not perfectly square. It is part of the Multi/Pak 88 trim family, which is designed to work alongside Slant/Fin H-Series heating elements for hot water or steam systems.
Designed for use with the Slant/Fin Multi/Pak 88 baseboard heating system, including installations using H-Series heating elements for hot water or steam. Intended for use at projecting wall corners in residential and light commercial installations.
Installation is typically performed by a licensed HVAC technician or plumber during trim-out of a baseboard heating system. The heating system should be fully shut down and depressurized before handling any baseboard components. Ensure the corner piece is aligned flush with adjacent baseboard sections before securing to avoid gaps or misalignment. Follow local mechanical codes and the manufacturer's installation instructions for all baseboard trim components.
