Which kind of tool is specifically designed to open double doors equipped with panic bars?

The tool specifically designed to open double doors equipped with panic bars is the J tool. This tool is engineered to maneuver through the space between the doors and manipulate the panic bar mechanism, allowing the doors to be opened more easily in emergency situations or when quick access is required, such as during firefighting or rescue operations.

The design of the J tool enables firefighters to hook onto the panic bar from the side of the door and push it in a way that releases the locking mechanism without needing to access the door handle itself. This is particularly useful in scenarios where rapid entry is necessary, as it streamlines the process of bypassing the panic hardware.

Other tools mentioned, such as a French curve, opening strip, and claw tool, do not possess the specific functionality required to operate panic bars on double doors. Each of these tools serves different purposes in emergency response scenarios, but when it comes to accessing double doors equipped with panic bars, the J tool is uniquely qualified for that task.
