The HVAC hand crimper has a durable handle with a non-slip grip for comfort and control. It includes an integrated lanyard hole for added safety when working at height. The spring-loaded lever mechanism helps reduce hand fatigue and overexertion during extended use. Crimper Material: The head is constructed from A3 steel plate, and the handle is made of 45# steel plate, providing durability and resistance to harsh working conditions. One-Hand Operation with Safety Lock: This gutter crimping tool includes an integrated safety latch that keeps the tool compact for easy storage and protects the crimping head from damage. Versatile Use: The 5-blade design is suitable for ductwork, downspouts, gutters, metal pipes, round pipes, furnace pipes, and other sheet metal applications requiring a secure crimp connection.
