The IBeam rail’s hourglass profile contributes to the clamp's ability to resist flex over a greater clamping span. Designed to meet the demanding needs of industrial workloads, IBeam is very stiff and much better at resisting bend or twist over a long distance than other clamps. For powerful clamping of all types, where strength and straightness over a distance are crucial. BESSEY® IBeam clamps are ideal for high-demand industrial & institutional woodworking. Available in lengths from 24" to 96"
