Lukjan CA7416204TSW Top Access Filter Frame Box 16x20

Product Description

The LUKJAN CA7416204TSW is a top-access filter frame box designed for use in residential and light commercial HVAC systems. It accepts a 1-inch filter and features a 4-inch-wide frame body with a swing door that allows quick, tool-free filter changes from the top of the unit. This frame box is installed inline on ductwork or at the air handler to house and secure flat-panel filters in place during system operation. HVAC technicians and installers use this type of filter frame to create a dedicated filter section in supply or return duct runs.

This filter frame box is suited for residential forced-air systems and light commercial HVAC applications where a 16-inch by 20-inch filter is required. The top-access swing door simplifies filter maintenance in tight spaces or overhead installations where side access is limited. It fits into duct systems as a fixed filter housing, keeping the filter properly seated and preventing air bypass during operation.

Key Features

• Top-access swing door allows filter changes without removing the frame from the duct
• Accepts standard 1-inch flat-panel filters in 16-inch by 20-inch size
• 4-inch-wide frame body provides a secure housing for the filter slot
• Designed for inline duct installation on residential and light commercial forced-air systems

Compatibility

Designed as an OEM-style universal filter frame box for residential and light commercial forced-air HVAC duct systems requiring a 16-inch by 20-inch by 1-inch filter.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified installer. Power down the air handler or furnace at the disconnect before cutting into or connecting to ductwork. Secure the frame to the duct with sheet metal screws and seal all seams with UL-listed foil tape or mastic per applicable mechanical codes. Confirm the swing door opens fully and the filter seats flush with no air gaps before restoring power.
