71800
Product ID 71800 Product Name 18" Locking C-Clamp UPC 726896718002 GTIN 10726896718009 Product Copy Engineered for High-Clamping Force Applications The Palmgren 18" Locking C-Clamp is designed to deliver repeatable holding power across demanding fabrication, welding, and woodworking operations. The heavy-duty forged steel frame maintains rigidity under load while the adjustable locking mechanism provides controlled clamping pressure across a wide range of material thicknesses. The Heavy-Duty Clamping Solution for Large-Scale Fabrication When your project demands a firm, reliable grip on large workpieces, the Palmgren 71800 18" Locking C-Clamp delivers the holding power and versatility professionals need. Built for welding shops, fabrication facilities, and metalworking operations, this clamp combines an 18-inch jaw capacity with a hardened steel body to handle the toughest clamping tasks with confidence. Built for Fabrication and Assembly Operations Designed for professional shop environments, this locking C-clamp provides secure positioning during welding, grinding, cutting, and assembly work. The large jaw capacity supports oversized workpieces while maintaining stable clamping performance throughout extended operation. Heavy-Duty Steel Construction The forged steel body is engineered for long service life under repeated shop use. Heat-treated components improve durability and resistance to deformation while maintaining consistent locking performance during high-pressure applications. Controlled Pressure Adjustment The adjustable lead screw mechanism with 1/4" hex key drive allows operators to fine-tune clamping force based on material thickness and application requirements. This controlled adjustment helps maintain workpiece stability while reducing movement during fabrication processes. Key Benefits 18-Inch Jaw Opening Capacity The generous 18-inch opening handles large panels, thick stock, and oversized workpieces that smaller clamps simply cannot reach. Whether you're clamping steel beams, large assemblies, or thick plate, the 71800 provides the reach you need. Precision Locking Mechanism The screw-type locking adjustment gives you exact control over clamping pressure. Set your pressure once and lock it in — the clamp holds securely without drift or slippage during welding or grinding operations. One-Hand Release Trigger The built-in release trigger lets you open the clamp with a single hand, keeping your other hand free to manage the workpiece. This ergonomic feature dramatically improves workflow efficiency when repositioning parts. Hardened Steel Construction Manufactured from hardened steel, the 71800 resists deformation under heavy clamping loads and holds up to the heat, sparks, and mechanical stress of active shop environments. Ideal Applications Welding and tack welding large assemblies Metal fabrication and structural assembly Woodworking projects requiring wide jaw reach Holding fixtures during drilling, grinding, or cutting General industrial clamping tasks Heavy-duty repair and maintenance work Securing irregular workpieces during machining Product Features 18" maximum opening capacity for large workpieces.
