The HPC Power Wedge™ (PW-100) is a revolutionary auto entry device designed to aid in opening even the most difficult vehicles! The Power Wedge™ is a spring loaded compound lever that safely spreads a vehicle door away from the body, allowing for the easy entry of a "Through the Car" opening tool. The Power Wedge™ slides into the opening between the vehicle's door and frame at the top of the door. The rubber-coated ends protect the vehicle from scratches and the adjustment knob allows you to control how wide you need the door to open. Simply turn the knob clockwise and watch as the door slowly opens giving you room to use a car opening tool to open the vehicle safely from the inside.
