Front Vise quick release, large

Designed for easy adjustment, these traditional  bench vises have steel spindles and large cast  iron faces. The movable jaw has a slight inward cant to let the top of the jaw touch fi rst as it  closes. Under clamping pressure, this jaw becomes parallel with the fi xed jaw, providing more consistent pressure over the entire jaw face so work is held securely. The quick release is designed for one-handed operation; the screw is disengaged by two counterclockwise turns of the handle, allowing work to be held with one hand as the vise is quickly adjusted with the other.Both jaws are through-drilled for wooden faceplate attachments. The moving jaw has an adjustable steel dog. The large vise requires a  space 20Й long for the spindle and guide rods. The medium and small sizes require 18Й and 13Йrespectively. All are excellent for equipping a new bench, or adding to an existing one.  Components of quick release system ( Picture . 1) :1. Handle2. Quick-Release Nut3.
