Ratchet Hold Down Clamp

The UJK Ratchet Hold Down Clamps are quick to position and provide exceptionally secure workholding on UJK Multifunction Workbenches, MFT-style tables and bespoke UJK Parf Guide System worktop. The Ratchet Hold Down Clamp handles a wide range of workholding tasks, with a 60 mm throat depth and 90 mm maximum working height, on a workbench maximum thickness of 30 mm. 

The ratchet action makes it easy to apply the exact pressure needed, without over-tightening, while the non-marking swivel pad applies even pressure and helps protect the workpiece. The spigot drops directly into a 20 mm dog hole, with a support plate fastening above and underneath the bench, spreading the clamping load across the bench surface. As the ratchet mechanism can generate exceptionally high clamping force, using the support plates will prevent the spigot from damaging the dog hole.
The stainless steel spigot mount, locking knob and support plates are CNC machined for accuracy and durability. The 25 mm diameter top section of the spigot can also be used as a reference point, allowing a workpiece to be positioned and clamped at the same time.

Ideal for UJK Multifunction Workbenches, MFT-style tables and bespoke UJK Parf Guide System worktop.
