Abstract:
A snubbing jack includes a first telescopic member and a second telescopic member. A stationary plate and a movable plate are affixed to the telescopic members. The movable plate moves away from the stationary plate upon expansion of the telescopic member and moves toward the stationary plate upon contraction of the telescopic members. An intermediate plate is removably secured between the stationary plate and the movable plate.
