Knu-Vise Locking Series
The new Knu-Vise locking clamps are the first in the "P" series that feature a new safety locking system. The new clamp locking system is designed into the clamp linkage. They are built with durability in mind, capable of withstanding extreme impact and vibration without failure. There are two seperate open positions and the lock can only be released by releasing the secondary locking lever. - Patent Pending.
