Troubleshooting

Clamp does not slide freely on the bar

Clean the bar thoroughly with a dry cloth to remove sawdust or resin residue.

Jaw slips under pressure

Ensure the release trigger is fully engaged and the bar is free of oil or lubricant.

Protective pad falls off

Ensure the pad is snapped firmly onto the jaw housing; if it remains loose, check for debris trapped between the pad and the jaw.

Pros and Cons

Pros

  • Tool-free conversion from clamp to spreader
  • High 136kg clamping load capacity
  • Non-marring pads protect finished surfaces
  • Swivel jaws adapt to non-parallel workpieces
  • Easy one-handed operation

Cons

  • Limited to 300mm span capacity
  • Not suitable for heavy-duty industrial framing
  • Plastic release trigger requires occasional cleaning for smooth operation

Setup, Compatibility & Care

To convert the clamp to a spreader, simply slide the jaw off the bar, reverse its orientation, and re-insert it onto the opposite end of the bar. Ensure the square protective pads are properly snapped into place before use to prevent wood marking. Periodically wipe the steel bar with a clean cloth to remove dust, debris, and dried wood glue, as grit on the bar can interfere with the sliding mechanism. Do not use chemical solvents for cleaning, as these may damage the plastic components. When not in use, store the clamps in a dry, temperate environment to prevent the internal springs from losing tension.
