The DO IT 300039 is a 1-inch C-clamp built for general-purpose clamping tasks across a range of trade and workshop applications. The body is cast from malleable steel with a gray surface finish, and the screw is carbon steel with precision machining for smooth, consistent thread engagement. The swivel pad helps distribute clamping pressure evenly across the workpiece. This clamp is sold individually and is a practical addition to any technician or installer's tool kit. It carries a lifetime warranty from the manufacturer.
This C-clamp is suited for light to medium-duty clamping where a compact 1-inch jaw capacity is appropriate. Typical uses include holding pipe, conduit, sheet metal, or structural components during fabrication, assembly, or installation work. It is commonly used by HVAC technicians, plumbers, electricians, and general contractors for temporary workholding during service and construction tasks.
Designed as a general-purpose 1-inch C-clamp suitable for standard trade and workshop clamping applications.
C-clamps of this type are hand-tightened and require no special tools for installation. Apply clamping force gradually and evenly to avoid marring the workpiece surface. Do not use a wrench or pipe to extend the handle for additional torque, as this can damage the screw threads or exceed the clamp's rated capacity. Inspect the screw and swivel pad before each use for wear or damage.
