This is a device installers use as a portable telephone with alligator clips and specialized tone and probe capabilities. Invented by hardware store owner William H. Rubely in the late 's and initially called the "Tuckahoe Toggle Bolt" , the toggle bolt has been used whenever you need to mount something to a non-structural, hollow, thin wall where a screw would simply pull right out.
A toggle bolt has wings like a butterfly that fold closed against an internal spring to be inserted into the wall. Once through the wall, it snaps open and provides a secure are wide surface area to fasten an object to the wall using the attached a threaded screw.
You'd see it used in sheetrock or wood applications holding a fire alarm box, a speaker to ceiling tile, a bulletin board, etc. When the screw is removed, the wing simply drops behind the wall to the floor below and is abandoned. A box that is designed to be installed after the finished wall is installed. Old work boxes have ears, opposing corner tabs, integral to the box that press against the back side of the wall as the fastening screws are tightened.
Typically though of as the goo used in compression and split-bolt connections where aluminum wire is used, the PENETROX product is an oxide-inhibiting grease designed to create an air-tight and moisture resistant joint.
The goal is to prevent the oxidation or corrosion of the metal products used in the electrical connection. Depending upon the type of metals found in the joint, you would use a specific version of the product containing suspended particles designed for that metal. Type "B" contains Zinc particles and is used where the metals are all aluminum. It has found favor in a number of industries, such as Ham Radio operators, where the grease acts as a lubricant for threaded connections and reduces the chance of them seizing down the road.

A drawing from a side angle of a line to be reviewed by an engineer. In new or existing construction when a pipe must pass through a solid wall, local codes determine to what degree the opening between the outside of the pipe and the wall must be resealed. In some cases an expanding seal is required to guard against the spread of fire.
In others, the outside pressure of dirt or water requires a different, more permenant seal. Link-Seal Modular Seal was created to address the need to hydrostatically seal pipes up to 20 psig. These uses come about in vaults, manholes and when walls must be backfilled with soil or come under water pressure.
They are ordered in varying widths and lengths according to a highly specific formula based on the opening but all come shipped as a belt of interconnecting rubbler links. This belt is then wrapped around the pipe and slid into the wall opening. Once in place, the bolts in each link are tightened creating an expanding seal to protect against water and a range of chemicals.
