Product description
Maximum stability
The clamp forged from a single piece with moulded pressure plate is hardened, tempered and galvanised, making it highly durable and torsion-resistant. The optimised profile now allows greater extension with the same stability.
External handle
The handle is located behind the clamp's rail. This is specially conceived to allow the clamping and spreading of work-pieces which are not easily accessible.
Special V-grooved pressure plate
This sturdy pressure plate is made from high-grade cast iron, and can be tilted by up to 30°. The prism is ideal for clamping and spreading round or angular work-pieces.
Removable end stop
The end stop can be removed – to allow the sliding arm to be quickly turned around for spreading.
Areas of application
Metal construction
Locksmith work
For clamping and spreading in the smallest of spaces
Safety information
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.

Care instructions
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.
Clean and oil the pressure plate regularly.
If the rail is shiny, roughen both narrow sides with emery cloth (100 grain).
