The XTRWELD TCCC066900HD is a heavy-duty steel C-clamp rated for 6900 psi of clamping pressure with a 6-inch clamping capacity. Built for demanding fabrication and welding applications, this clamp delivers reliable holding force on workpieces that require firm, stable positioning during cutting, grinding, or welding operations. The deep-frame design provides 3.6 inches of throat depth, giving the user clearance to reach inset areas on larger workpieces. The gray steel construction is suited for shop and field environments where durability under mechanical stress is required. Welders, fabricators, and ironworkers rely on this class of clamp for consistent performance across repetitive heavy-use cycles.
The TCCC066900HD is appropriate for structural steel fabrication, pipe fitting, and general metalworking setups in both shop and field conditions. Its 6-inch jaw opening accommodates a wide range of material thicknesses, making it useful for tacking, fixturing, and clamping assemblies prior to welding or permanent fastening. This clamp is sold individually and is a practical addition to any welding or fabrication toolset where high clamping pressure and throat clearance are priorities.
Designed as a general-purpose heavy-duty C-clamp for welding, fabrication, and metalworking applications requiring high clamping pressure and extended throat depth.
C-clamps of this pressure rating are typically used by welders, fabricators, and pipefitters during fixturing and tacking operations. Ensure the clamp screw is tightened by hand to full engagement before applying final torque with a wrench or handle extension. Do not use this clamp to support suspended loads or as a primary structural connection. Inspect the screw threads and swivel pad for wear before each use in high-cycle environments.
