A novel, simple, inexpensive and universal device and method for manipulating a magnetic object with at least a portion thereof having a substantially prismatic shape with side surfaces and an end surface such as a fastener, bolt, nut, plug, screw, and the like is disclosed. One embodiment of the device includes a head assembly having a magnetic field. The head assembly includes a body and a magnetic pole piece. The body serves to support the magnetic pole piece and the magnetic pole piece is configured to contact no more than two side surfaces of the magnetic object. The magnetic pole piece is also constructed and arranged to concentrate and shape the magnetic field into the magnetic object. The head assembly is further configured to be spatially open opposite from the magnetic pole piece so as to receive and contact the magnetic object.

A ratcheting spreader system includes a construction frame that has a pair of lateral arms. A spreader has a first half is slidably coupled to a second half. The spreader includes an urging unit extending between the first half and the second half. The urging unit may be manipulated thereby spacing the first half a selected distance from the second half. The spreader is selectively positioned between the lateral arms such each of the first half and the second half engages an associated one of the lateral arms. The urging unit urges each of the lateral arms a precise distance apart from each other. Thus, the lateral arms may be secured during construction.

A multipurpose tool can include a combination of tools desirable for working with storage drums, valves, gas containers, or other items that may be present in a compromised environment. The tool can include two tool head assemblies. A feature of first tool head assembly is an adjustable wrench. Features of the second tool head assembly can include a combination of large bung wrench with a gas valve shut off. The tool can include additional tool implements that may be utilized in the compromised environment to maximize ease of use and safety of the user.

There is provided a sprinkler head having a structure in which steps such as removing and reattaching a protecting cap are eliminated at the time of construction of the sprinkler head, where a cylindrical member is installed on an outer portion of a sprinkler head body and the protecting cap is installed between the sprinkler head body and the cylindrical member. A cylindrical member and a sprinkler head body are installed by being engaged so as to be rotatable together, a protecting cap configured to protect the sprinkler head body from an external force is locked to the cylindrical member. The protecting cap is provided with a space in which a tightening tool for connecting a sprinkler head to a water supply pipe is capable of locking to a tightening tool engaging portion.
