Description
The mechanical pull box, Part No. 81-871403-000 (Figure 4-23), is a cable connected, pull handle-type remote release station used for actuating carbon dioxide cylinders and associated directional (stop) valves. The pull box is designed to transmit a force via a 1/16-inch cable to the cable operated control heads attached to the pilot CO2 cylinders and the appropriate flow control valves. A hammer is attached to the pull box, and operation is accomplished by breaking the glass front with the hammer and pulling the handle.
