Lukjan CA7416257SW Side Load Filter Frame Box 16x25

Product Description

The LUKJAN CA7416257SW is a side-load filter frame box designed for residential and light commercial HVAC systems. The unit accepts a standard 16 by 25 inch filter through a swing door on the side, allowing filter changes without disconnecting ductwork. The box measures 7 inches in depth and is built around a 1-inch filter slot. Licensed HVAC technicians and sheet metal installers use this type of filter box to create a serviceable filtration point on a furnace or air handler return-air section. Its universal design makes it adaptable to a range of duct configurations where side-access filter service is preferred.

The CA7416257SW fits into the return-air plenum or duct run of a forced-air furnace or air handler installation. It is particularly useful in residential applications where equipment is located in closets, utility rooms, or attic spaces where filter access from the front or bottom is restricted. The swing door provides clean, tool-free access to the filter at service intervals. This frame box is classified as a universal filter frame box and is commonly installed during new construction or system retrofits where a dedicated filtration station is needed in the return duct system.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the furnace or air handler at the disconnect or breaker before beginning work on the return-air section. The frame box should be secured to the duct or plenum per local mechanical code requirements, and all joints should be sealed to prevent unfiltered air bypass. Follow applicable IFGC and local mechanical codes for duct connections in gas-appliance installations.
