The tool trap serves as a signaling device as well. It is an emergency device , helps prevent a loss of a tool or a scraper into a well after slickline or wireline part/ break as a result of hitting a stuffing box installed in the top section of lubricator. As a rule, the tool trapping and signaling device is used as part of a lubricator string above a ram preventer. It signals that the tools have entered an upper lubricator tube.

The trap has a flap which looks similar to a “swallow tail”. The flap is set open manually by an operator to allow a tool string or a scraper be run into a well. Once the tools have passed the trap section, an operator manually sets the trap in a “closed” position. Then, the trap will be led in a "closed” position by the spring which applies force to automatically close the flap.

When the flap is in closed position, braided cable or slickline can be freely pulled up through the trap. As soon as a cable head or a rope socket touches a lower part of the flap, it opens and allows the tools passing through the trap. After the tools have passed the flap and enter a lubricator pipe, the flap automatically swings shut. It remains closed under force applied by the spring mechanism not letting the tools drop down.

In case of hitting or breaking wireline cable or slickline the tools will be caught above the flap preventing a loss of the tools in a well.
