Lukjan CA50F291720A Furnace Box with Filter Slot 29x17x20

Product Description

The LUKJAN CA50F291720A is a furnace box with a built-in filter slot, designed for use in residential and light commercial HVAC installations. This sheet metal furnace box measures 29 inches by 17 inches by 20 inches and serves as a transition fitting between the furnace or air handler and the duct system. The integrated filter slot allows for in-line filter placement without a separate filter rack, streamlining the installation. HVAC technicians and sheet metal contractors use this type of fitting when roughing in or replacing ductwork connected to a forced-air system.

The CA50F291720A is suited for forced-air heating and cooling systems where a filter-slot furnace box is required at the equipment connection point. Its dimensions make it appropriate for mid-to-large residential furnace or air handler applications. This fitting is typically installed at the return-air side of the equipment, providing a clean, secure transition from the plenum or duct run to the unit cabinet while also housing the system filter.

• Nominal dimensions of 29 x 17 x 20 inches suit mid-to-large forced-air systems

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the furnace or air handler and shut off all associated utilities before fitting or modifying ductwork connections. Secure the box using sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant in accordance with local mechanical codes.
