The bessey gs k classix 1000mm clamp with 120mm throat depth represents the largest capacity in this series, perfect for substantial fabrication projects, large frame assemblies, and workshop applications requiring maximum reach. This extended capacity clamp excels in furniture manufacture, structural assemblies, and large scale joinery work. Maintaining the full 5000 n clamping force across its 1000mm span, this clamp delivers consistent pressure distribution essential for large workpieces. The tempered steel construction throughout ensures the clamp remains straight and true under load, whilst the substantial 27mm x 13mm rail provides the rigidity required for this extended length. The sliding arm mechanism allows efficient positioning across the full metre length, whilst the tommy bar's rounded ends facilitate comfortable force transfer without hand fatigue.
