DUCTMATE

DUCTMATE is a manufacturer of duct access doors and related hardware for HVAC and industrial ductwork. The product line is built around two primary families: flat access doors for rectangular ducts and curved access doors for round ducts. These doors provide inspection, cleaning, and maintenance access points in duct systems, and are specified by mechanical engineers, sheet metal contractors, and maintenance teams. DUCTMATE access doors are constructed from steel, typically in 18, 20, 22, or 24 gauge, and are available with fiberglass insulation. Flat models for rectangular ducts feature double cam latches and tab-in hinges, while curved models for round ducts use knob-style fasteners or thumbscrews. Temperature ratings vary by model, with standard flat doors rated to 175°F and high-temperature curved doors rated to 200°F. Curved doors are sized to fit specific round duct diameters, from 10 inches up to 32 inches, with opening sizes ranging from 4 in x 8 in to 18 in x 24 in. Mounting studs are provided on many models for secure installation. 3G Electric supplies the DUCTMATE line as part of its industrial equipment catalog, offering access to 95 SKUs that cover flat and curved configurations. The catalog includes standard and high-temperature variants, with options for different duct shapes, sizes, and fastening methods. Technical buyers can compare specifications such as gauge, insulation, temperature rating, and duct compatibility to select the appropriate door for their application. 3G Electric supports the line with product data and quotation services for procurement and maintenance teams.

Frequently asked questions

Common questions about DUCTMATE from 3G Electric.

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

DUCTMATE flat access doors are designed for rectangular ducts and feature a flat profile with double cam latches and tab-in hinges. Curved access doors are designed for round ducts and have a curved profile to match the duct diameter, using knob-style fasteners or thumbscrews. Flat doors are typically rated to 175°F, while high-temperature curved doors are rated to 200°F. Both types provide access for inspection, cleaning, and maintenance.

What temperature ratings are available for DUCTMATE access doors?

DUCTMATE access doors have temperature ratings that depend on the model. Standard flat access doors, such as SKU 6EKC6, are rated for a maximum temperature of 175°F. High-temperature curved access doors, such as those in the 29VJ series, are rated to 200°F. These ratings should be considered when selecting a door for applications involving heated air or industrial exhaust.

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

DUCTMATE curved access doors are sized to fit specific round duct diameters. For example, SKU 29VJ86 fits 10 to 11 inch ducts, while SKU 29VJ93 fits 29 to 32 inch ducts. The opening size also varies, from 4 in x 8 in to 18 in x 24 in. Determine your duct diameter and required opening size, then select the corresponding model. Mounting studs and fastening type (knobs or thumbscrews) are also specified per model.

What materials and construction are used in DUCTMATE access doors?

DUCTMATE access doors are constructed from steel, with gauges ranging from 18 to 24 depending on the model. Many models include fiberglass insulation. For instance, SKU 6EKC6 is 24 gauge steel with fiberglass insulation, while SKU 29VJ93 is 18 gauge steel. Fastening options include double cam latches, knob-style fasteners, and thumbscrews. Mounting studs are provided on many curved models for secure installation.

Are DUCTMATE access doors suitable for high-temperature industrial exhaust applications?

DUCTMATE high-temperature curved access doors are rated to 200°F and are used in applications such as industrial exhaust or high-temperature ductwork. These models, including the 29VJ series, are constructed from steel and feature thumbscrew fasteners. They provide access for maintenance and inspection. For applications exceeding 200°F, consult the manufacturer's specifications or contact 3G Electric for assistance.
