Ideal for particularly challenging tasks, the original Bessey GRA claw clamp lets you clamp and stretch in even the most confined spaces. It can be used in narrow openings as well as for short projections. This is thanks to the clamp's unique clamping and spreading mechanism, which is located behind the rail. The GRA clamp also boasts a very robust construction, making it ideal for welding and assembly environments.
