3/4" x 4' Hydronic Element for Lo-Trim Baseboard

Argo Lo-Trim II Hydronic Heating Element – 4 Ft. Baseboard Fin-Tube Assembly

The Argo 55LT27-E-4 is a 4-foot hydronic baseboard element engineered for integration with Lo-Trim II enclosures. This assembly features a 3/4-inch copper tube with aluminum fins, mechanically bonded for optimal heat transfer in closed-loop hot water heating applications. The unit is supported by a galvanized steel bracket, designed for secure placement and alignment during installation.
