Especially locks of the new generation with end-to-end bolts are appropriate for this kind of opening set. Just install the lifting tool between the door and the door handle plate, in order to obtain the necessary gap that allows introducing the square bolt tool. Actuate the bolt with the tool in order to unlock the door latch. The PKI 9705 door latch opening set is also appropriate for double rabbet doors and self-closing systems. Our handle plate lifting tool can be used on all door systems with enough ridges that allow placing it precisely and to exert force on it. The PKI 9705 Door Latch Opening Set tools are delivered in a solid hard-cover plastic case with inlays.
