1.00″ X 100′ DUCT STRAP 26 GUAGE – Duct straps in construction are used to secure and support HVAC (heating, ventilation, and air conditioning) ductwork in place. These straps are typically made from metal, such as galvanized steel, and are designed to wrap around ducts, holding them securely against walls, ceilings, or other structural supports. They play a key role in ensuring the stability, alignment, and proper functioning of the duct system.
