FAQs

What is the maximum opening capacity?

The clamp has a maximum opening capacity of 200mm.

Can I use this for metal welding?

While the cast iron is robust, high-heat welding may damage the protective plastic caps and the wood handle. It is best suited for woodworking or general assembly.

How much force does this clamp provide?

It provides up to 5500N of clamping force, equivalent to 561 kg.

Are the clamping caps removable?

Yes, the protective caps can be removed if you need direct metal-on-metal contact, though using them is recommended to prevent damage.

Is the handle replaceable?

The handle is an integrated ergonomic wood component designed for high durability; contact the manufacturer if service is required.

Troubleshooting

The sliding jaw slips under pressure

Clean the serrated rail with a stiff brush to remove grease or sawdust buildup.

The screw handle is difficult to turn

Clean the threaded spindle and apply a small amount of machine oil or dry PTFE lubricant.

Clamping caps fall off

Ensure they are fully seated on the jaw edges. If they are loose, replace with official Bessey spare pads.

Pros and Cons

Pros

  • Extremely durable cast iron construction
  • High 5500N clamping force capacity
  • Ergonomic handle reduces user fatigue
  • Protective caps protect sensitive work surfaces

Cons

  • Fixed 200mm capacity may limit larger projects
  • Weight of 770g is robust but adds to tool kit bulk
  • Not intended for extreme high-heat welding environments

Setup, Compatibility & Care

To ensure longevity, keep the sliding rail free of sawdust and debris, as build-up can interfere with the serration grip. Periodically apply a thin, dry lubricant to the screw spindle to maintain smooth operation when tightening. When clamping, always ensure the workpiece is centered on the clamping pads to distribute pressure evenly and prevent twisting. Avoid using the clamp as a lever or spreader, as this can bend the rail and compromise the tool's structural integrity. Store the clamp in a dry, temperate environment to prevent oxidation of the metal surfaces.
