5' Complete Assembled for Lo-Trim Baseboard, 300 BTU

Argo 55LT27-5 Lo-Trim II Hydronic Baseboard – 5 Ft Section, Galvanized Steel Enclosure with Aluminum Fin Tube Element The Argo 55LT27-5 Lo-Trim II hydronic baseboard is a 5-foot panel section designed for closed-loop hot water heating applications in residential and light commercial environments. This model features a low-profile cabinet constructed from galvanized steel, finished with a baked white powder coat, and includes an internal fin-tube element for reliable and efficient thermal output. Each unit is equipped with a 3/4" copper tube and high-conductivity aluminum fins, mechanically bonded for optimal heat transfer. The enclosure supports snap-on accessory integration, including end caps, corners, splices, and brackets, providing installation flexibility for continuous baseboard runs or segmented zones. Technical Specifications: Model: 55LT27-5 Length: 5 ft nominal Tubing: 3/4 in CTS copper Heating Element: Copper tube with aluminum fins Cabinet Material: Galvanized steel Finish: White powder coat (baked enamel) Heat Output: Approx. 300 BTU/hr per linear foot (dependent on system water temperature, flow, and ΔT) Features & Application: Low-Profile Configuration – Suitable for perimeter wall runs where vertical clearance is restricted Durable Steel Cabinet – Formed and coated to resist corrosion and mechanical wear in field conditions High-Efficiency Fin-Tube Core – Delivers uniform convective heat with rapid thermal response Snap-On Accessory Compatibility – Simplifies field assembly and end-to-end alignment Quiet Passive Operation – No mechanical components; relies on natural convection for silent performance Installation Considerations: Mounts directly to finished walls using standard bracket spacing and wall fasteners Requires proper spacing from floor and overhangs for free airflow and thermal efficiency For optimal performance, install on a closed-loop hydronic system with design water temperatures typically between 140–180°F Enclosure is field-serviceable; front panel and damper are accessible for cleaning and adjustments Must be installed in compliance with local building codes and mechanical specifications The Argo Lo-Trim II series is ideal for contractors working on retrofit or new construction projects where compact form, reliable performance, and seamless appearance are critical. This 5-foot section is compatible with other lengths in the series and integrates into multi-zone hydronic heating systems with minimal setup time.
