Duct Access Door 16x16 Inches

The Ductmate GRFDH16GA is a square duct access door designed for HVAC systems. It fits a 16-inch by 16-inch opening and features a tab-in hinge style for installation. The unit is constructed with 24-gauge material and includes fiberglass insulation for thermal performance.

Replaces Damaged or Missing Access Panels

This door upgrades existing ductwork where an inspection or cleaning port is required but absent or broken. The jump is worth it when routine maintenance demands a secure, insulated seal that withstands temperatures up to 175 degrees Fahrenheit. The single cam latch provides reliable closure without specialized tools.

Sustained Load Behaviour Under Heat

Under continuous exposure to maximum rated temperature, the fiberglass insulation maintains its integrity and the 24-gauge steel resists warping. The tab-in hinge design holds alignment through thermal cycling without binding. The transparent colour allows visual confirmation of seal condition without opening the door.

Questions about this item

What size duct opening does the 16 by 16 inch tab-in access door fit?

The door is designed for a 16 inch by 16 inch square duct opening and uses a tab-in hinge style for mounting.

How do you install the tab-in hinge and what step is often missed?

Insert the tabs into the pre-cut duct opening and secure the 2 inch mounting studs; the cam latch must be engaged to seal the 2 1/8 inch thick insulated panel.

Will the fiberglass insulation inside the 24 gauge steel door need replacement over time?

The fiberglass insulation is rated to 175 degrees F and is built into the door panel; it is not a separate replaceable component under normal conditions.
