The Vevor 2-pack 50" parallel clamp set is built for woodworking and metalworking tasks that require strong, even clamping pressure. Each clamp features a large 50" jaw opening and a 1100 lb load limit for secure holding during cutting, joining, and assembly. The handles are made from high-strength PA6+GF30 plastic, while the slide bars use durable 45# carbon structural steel. An extended rod design provides added versatility for working with different material thicknesses. This set is suited for projects involving wood products like tables, chairs, and cabinets as well as steel materials.
