Frequently asked questions

Common questions about DUCTMATE from 3G Electric.

What temperature ratings are available for DUCTMATE access doors?

DUCTMATE access doors are available in standard models rated up to 175°F or 200°F, and high-temperature models rated up to 2,300°F. The high-temperature variants use steel construction with thumbscrew fasteners and mounting studs, suitable for applications such as boiler flues, exhaust ducts, or industrial ovens. Standard models typically use double-cam or knob closures with fiberglass insulation. Always verify the specific model's maximum temperature rating against your system's operating conditions.

How do I select the correct DUCTMATE curved access door for my round duct?

DUCTMATE curved access doors are designed for specific duct diameter ranges, such as 10 in to 11 in, 19 in to 20 in, or 45 in to 48 in. The part number indicates the duct size range and opening dimensions. For example, model GRDRI12820GA fits ducts 19 in to 20 in with an 8 in x 12 in opening. Measure your duct's outer diameter and confirm the door's compatible range. Also check the gauge (22 ga or 18 ga) and closure type (knobs or thumbscrews) to match installation requirements.

What is the difference between DUCTMATE flat and curved access doors?

Flat access doors are designed for rectangular ducts and feature a flat panel with a tab-in hinge and double-cam or thumbscrew closure. Curved access doors are contoured to fit round ducts and use knob or thumbscrew fasteners with mounting studs. Both types are made of steel with fiberglass insulation, but curved doors are sized by duct diameter range, while flat doors are sized by panel dimensions (e.g., 14 in x 18 in). Choose based on your duct shape and access location.

What hardware is included with DUCTMATE duct hangers?

DUCTMATE duct hangers include a wing nut and lock washer for securing the hanger to strapping. The hanger is made of steel with a 1-inch width and is rated for 260 lb capacity. They are compatible with 20 ga strapping and designed for round ducts from 6 in to 12 in diameter. The hanger itself does not include strapping; you must supply the appropriate strapping material for your installation.

Can DUCTMATE access doors be used in high-temperature industrial environments?

Yes, DUCTMATE offers high-temperature access doors rated up to 2,300°F, such as models GRD1814F2GA and GRD1814ULBI. These doors use steel construction with thumbscrew fasteners and mounting studs, and are available in gauges from 11 ga to 16 ga. They are suitable for applications like furnace exhaust, kiln ducts, or high-temperature process air systems. Standard models are not rated for such temperatures; always confirm the model's temperature rating before installation.
