The "tilt-in" 2-piece connector for non-metallic sheathed cable (a.k.a. Romex™) is a labor saving design that lets the electrician clamp the connector onto the cable, tilt it into the knockout and tighten down the screws. The screws both bind the connector to the enclosure and compress onto the cable making a secure fit. This eliminates the need to remove the locknut and re-attach it inside an often cramped box. Originally marketed by Tomic™. Available in conduit sizes from 1/2" to 1-1/2", (see also 'Butterfly Connector'; 'Tomic').
Metal box, usually 2" - 3-1/2" deep with various mounting from ears, nail-on, to masonry
When used with AC cable or Greenfield, Anti-Short ® bushings protect the wires from being chafed by the roughs end of the armor at the point of connection. NEC article 333-9 requires their use on AC (armored cable). They are placed between the outer metal armor and the conductors forming a protective shield at the point where the wire is bent during final connection. In the trade, they are referred to simply by their sizes 0 through 8 depending on the size of the cable or Greenfield.
Basket type pulling grip where wire mesh tightens over wire when pulled.
Connects two pieces of threaded rigid conduit when one piece can't be turned. Comes in aluminum, steel, malleable iron and zinc/die-cast construction in sizes from 1/2" to 5" If the same thing needs to be done for non-threaded pipe, you would use a threadless compression coupling.
An old term for a Fillister Head Screw.
Service Entrance cable which picks up where the utility service drop leaves off. Typically, it connects at the top of the service mast with utility rated bug nuts and runs down to the meter base. From the meter, it is usually used to enter the building and connect to the distribution panel. Sometimes you may see it used on branch circuits as permitted by the National Electrical Code.

When a manufacturer says Beam Clamp, they mean the family of clamps that attach members to a steel support beam. While there are many different kinds of beam clamps, the Window Clamp is the beam clamp with U-bolts. Whether you use Kindorf, PowerStrut, B-Line or some other strut manufacturer, they all offer Window Clamps of similar construction because there is generally only one way to mechanically make these things happen. As an aside, when a distributor or electrician refers to a Beam Clamp, they typically mean the "C" style clamp that screws tight to the flange of a beam and has a threaded hole to accept threaded rod. The Window Clamp, however, is the style that U-bolts the strut to the support beam.
