Corrosion Resistance: 304 stainless steel provides 500+ hours of salt spray resistance (ASTM B117), suitable for humid spaces like commercial kitchens and basements.
Load Capacity: Each clamp supports static loads up to 250 lbs (113 kg) without deformation, maintaining duct stability under thermal expansion.
Quick Installation: Pre-drilled mounting holes and adjustable bolt slots reduce installation time by 30% compared to traditional clamps.
Temperature Tolerance: Operates reliably in -40°C to 200°C (-40°F to 392°F), withstanding HVAC system temperature fluctuations.
Commercial Buildings: Secures supply/return air ducts in offices, hospitals, and shopping malls, preventing vibration-induced noise.
Industrial Facilities: Used in manufacturing plants with high dust or moisture levels, ensuring duct alignment in production areas.
Residential HVAC: Installed in attic and crawl space ductwork, resisting corrosion from condensation.
Q: Can these clamps be used with insulated ducts?
A: Yes, the saddle design accommodates insulation thicknesses up to 2", with rubber gaskets available to prevent insulation compression.
Q: What fasteners are recommended for installation?
A: Use 1/4" stainless steel lag screws for wooden framing or expansion bolts for concrete, ensuring minimum embedment depth of 1.5".
Q: Are they suitable for vertical duct runs?
A: Yes, when paired with anti-slide washers, they provide secure support for vertical ducts up to 12" in diameter.
