Fortress 84102 Inside Vertical Elbow 4.5 Inch 90 Degree

Product Description

The FORTRESS 84102 is a 90-degree inside vertical elbow for use with 4.5-inch lineset cover systems. It is designed to route a lineset cover around an inside corner in a vertical orientation on the exterior of a structure. This fitting connects to compatible duct sections of the Fortress lineset cover series, allowing a clean, finished appearance where refrigerant lines, electrical wiring, or condensate drain lines transition around a wall corner. HVAC technicians install this fitting as part of a complete lineset cover run during mini-split or split-system air conditioner installations. The part is manufactured in the USA and is finished in white.

This elbow is used in residential and light commercial HVAC applications where split-system linesets are routed along the outside of a building. It is suited for inside-corner transitions in vertical runs, where the lineset cover must change direction without exposing lines to weather or mechanical damage. The Fortress lineset cover series is designed to offer durability and field practicality at a moderate cost, bridging the gap between basic lightweight covers and higher-cost alternatives. This fitting corresponds to the LCI122W configuration in the Fortress series.

Installation Notes

This fitting is installed by HVAC technicians as part of a lineset cover system on split-system or mini-split installations. Power to the indoor and outdoor units should be shut off at the disconnect and breaker before routing or securing lineset covers near electrical wiring. Fittings are typically secured with manufacturer-supplied fasteners or appropriate exterior-rated screws. Follow local mechanical and building codes for lineset cover installation on exterior walls.
