Slant-fin 57188308000 Inside Corner 90 Degree Baseboard Cover

Product Description

The SLANT-FIN 57188308000 is an inside corner cover designed for use with the Multi/Pak 88 baseboard heating system. This one-piece snap-on component provides a finished, clean transition at 90-degree interior wall corners where baseboard heating elements meet. Intended for deluxe residential and light commercial installations, it accommodates the Multi/Pak 88 enclosure profile and bridges gaps up to 2.5 inches on each wall surface. Licensed HVAC technicians and plumbers install this trim piece as part of a complete baseboard heating enclosure assembly.

The Multi/Pak 88 system is suited for hot water and steam heating applications in residential and light commercial settings. Its design permits higher water velocities, lower pump loads, and longer loop runs compared to standard residential baseboard configurations. This inside corner piece is used wherever the baseboard run changes direction at a 90-degree interior corner, making it essential in rooms with limited straight wall runs or constrained layouts where a clean enclosure finish is required.

Installation Notes

Installation is performed by licensed HVAC technicians or plumbers as part of a complete baseboard heating enclosure assembly. The heating system should be shut down and cooled before handling enclosure components near active heating elements. The snap-on design requires no special tools, but verify wall gap dimensions do not exceed 2.5 inches on each side before fitting the corner piece.
