Maximum stability

The optimised profile shape guarantees greater clamping force build-up in the shortest time, while maintaining greater stability and safety. The fixed clamp forged from a single piece with moulded pressure plate is hardened, tempered and galvanised, making it highly durable and torsion-resistant.

  • Foldable by 90°, which provides additional leverage when tightening - and thus means less effort for the user
  • Can be rotated 360° when folded, which means that the user does not get caught on the rail during the clamping process and can therefore clamp more quickly than is the case with other competitor models
  • in hard-to-reach places, the "disturbing" handle can simply be folded away
Forged sliding arm

The sliding arm allows for more efficient transfer of force. As a result of its more linear transfer of force, the new U-shaped sliding arm offers maximum security with the heaviest of loads. You can rely on that.

  • thanks to fixed bracket, forged in one piece, tempered and galvanized, with molded-on pressure plate, the special springy characteristic of the all-steel screw clamp is achieved. The advantages: On the one hand, the pressure can be perfectly matched to the requirements of the workpiece. On the other hand, all-steel screw clamps are less sensitive to vibrations, which is why the clamps do not have to be retightened as quickly.

Pressure plate

For enhanced serviceability the pressure plate can be changed with no need for tools. It can be replaced very easily and quickly.

Smooth‐running spindle

The surface‐coated spindle with acme thread is particularly smooth‐running, and does not bind. For even smoother, more efficient work.

  • Interior fittings
  • Metal construction
  • DIY
  • Furniture and joinery works
  • Locksmith work
  • For clamping resiliently, elastically and powerfully
  • Space-saving and convenient clamping
  • Clamping tools are not suitable for lifting, pulling or transporting.
  • Clamping tools may only be clamped manually without using any auxiliary tools.
  • Improper use can cause personal injuries or material damage.
  • Never change or modify clamping tools. Only use them in their original condition. Only use original‐spare parts if required.
  • Fixed and sliding bracket made of tempered steel, galvanised
  • Spindle with trapezoidal thread in rolled steel, burnished
  • Handle made of 2-component plastic
  • Pressure plate made of steel, cold pressed, galvanised
  • Regular maintenance is necessary - only then can a secure hold be guaranteed (no slipping of the sliding bracket)
  • Clean the rails with solvent
  • Always keep the rail free of grease, oil or dried glue, waxes and silicone-based release agents
  • Clean and oil the spindle regularly
  • If the rail is shiny, roughen both narrow sides with emery cloth (100 grain)
  • Clean and oil the pressure plate regularly
