The Irwin Record 135/9 Heavy-Duty Sash Clamp provides an exceptional 1650mm (66in) clamping capacity, the largest in the range and designed for the most demanding large-scale woodworking projects. This extended reach is ideal for wide tabletops, long workbenches, large door assemblies, and substantial joinery work where maximum span is essential whilst maintaining professional-grade clamping force and control. Built with the proven heavy-duty 32 x 6mm bar section, this clamp delivers outstanding rigidity across its full length, resisting deflection even under significant load.
