Duct G Clamp – Detailed Description
A Duct G Clamp is a sturdy mechanical fastener used to hold, align, or support sheet metal ducting and fittings during HVAC installations and maintenance. Shaped like the letter “G”, this clamp features a threaded screw mechanism that provides adjustable, secure clamping pressure without damaging the surface of the ducts.
These clamps are commonly used for temporarily holding duct sections together during sealing, riveting, or screwing operations, especially in rectangular or spiral ductwork systems. Their robust steel construction and high-pressure threads make them ideal for construction environments, workshop use, and on-site HVAC fabrication.
Easy to use and highly reliable, Duct G Clamps help maintain proper alignment and structural stability while reducing vibration during fastening.
