A forcible access tool for opening a door from its frame. The tool includes a linear actuator, specifically an hydraulic cylinder, comprised of an outer casing and an extensible and retractable axial rod. A stationary jaw member is secured to the outer casing and a movable jaw member is secured to the rod to be movable relative to the stationay jaw member between a fully retracted home position and an extended position. A guide sleeve is secured to the outer casing of the hydraulic cylinder and slidably receives a guide pin which is secured to the movable jaw member. The guide sleeve and pin combination prevents relative angular pivoting or rotation of the jaw members and maintains longitudinal axial alignment of the rod and outer casing during operation of the tool to open a locked or obstructed door. In use, the stationary jaw member is inserted between the closed door and its associated door frame. A hydraulic pump unit is operated to supply pressurized hydraulic fluid to extend the movable jaw relative to the stationary jaw and thereby force open the door.
