Image of 2016.015.002.34 - Raychem ShrinkSystems Kit, c. 1985-1990. This is a Raychem Corporation ShrinkSystems kit encased in clear plastic. The kit contains a paper brochure, a piece of wraparound heat shrink tubing, a perforated metal sleeve for connecting the tubing, two plastic cable ties, and what appears to be black electrical tape for holding a cable splice in place. The black wraparound tubing is held together with a tan rubber band, and the rest of the items are loose within the clear plastic bag. The brochure's front cover contains color photographs and text against a gray background. “Raychem ShrinkSystems  /  HEAVY-DUTY HEAT-SHRINKABLE PRODUCTS” is printed vertically along the left margin. “Raychem” appears in red and the rest of the text is black. Text at top reads, “Solve All Your  /  Insulating, Sealing and  /  Repair Problems.” Two small color images of a person heating wraparound tubing appear below the text, and a large color image of a heat torch shrinking tubing over a pipe fills the lower three-quarters of the page.
 
Jim Thompson notes that the kits were commercial products sold to electricians through electrical distribution centers and not designed for a specific client. The wraparound heat shrink tubing is constructed with a rectangular piece of irradiated plastic that has a hooked channel on each side. The two sides are secured together around an existing pipe by sliding a perforated metal sleeve over the two channels. This is called a “rail and channel” closure. Markings on the tubing indicate the appropriate main and tap cable sizes for use with the product. The concept of wraparound tubing became the basis of thousands of Raychem products.
For a repair, an electrician would start by stripping off a section from the main cable. Wire would be added and secured with cable ties. White release paper on the inside of the wraparound tubing would be pulled off exposing adhesive to help the material stay in place as the two sides were brought together and secured with the metal sleeve. A torch was applied to shrink the tubing first at the center and slowly moving to one end and then the other. Adhesive inside the wraparound would melt and provide a water proof seal and electrical insulation.

Image of 2016.015.002.37 - Raychem EZF 59/6 Cable Preparation Tool, c. 1990s. Used in cable television installation, this Raychem Corporation accessory was used to prepare and install connectors on series 59 and series 6 coaxial cables. 
The tool has two black plastic levers connected at a spring-loaded metal fulcrum. The jaws of the tool are rectangular with rounded edges. A red plastic section at the front of the jaws holds two metal blades. The upper handle of the tool tapers at top and bottom to a flat rounded end. The lower handle is rectangular and has a 0.25” hole through the side for use as a port measurement gauge. A metal cylindrical “dummy” cable port is located on the top of the tool. 
The first function of the tool was cutting through outer layers of coaxial cable. The user would squeeze the handles to open the jaws and place the end of a piece of cable into a v-shaped groove with a stop at one end. The handles would be released, closing the jaws around the cable, and then the tool would be rotated clockwise until it turned freely. Pressure could also be applied to the top and bottom of the jaws to cut through the cable jacket. After being cut, the outer layers of the cable could be removed by hand, exposing the conductive wire at the center. 
The second function of the tool would be to compress a connector and cable assembly.  The exposed wire at the end of a cable would be threaded through a channel in a piece of cable connector hardware. The connector and cable assembly would then be threaded by hand onto the metal “dummy” port on the top of the tool and tightened with a wrench to form a mechanical seal around the wire.

Image of 2016.015.002.43 - Raychem PolyStrip Wire Stripper Kit, c. 1960s-1970s. This is a Raychem Corporation PolyStrip wire stripper device in its original cardboard box with two cartridges of replacement blades. (A) The PolyStrip wire stripper has two gray metal levers that are joined at a fulcrum to create pincers with a set of "jaws" with blades at one end and spring loaded handles at the other. Squeezing the handles closes the blades around a piece of inserted wire. The handles are covered with insulating black plastic, and the blades are made from red colored polyarylene plastic. Clear adhesive labels with "Raychem" in white lettering are applied on the top side of the stripper near the blades and on the bottom side near the fulcrum. The two cartridges included in the kit are circular containers made from clear plastic that hold up to 10 red 1" x 0.25" blades in a radiating fashion. Cartridge (B) has 10 blades and cartridge (C) contains 6 blades. The wire stripper and the cartridges rest inside an insert in the cardboard box that inhibits them from sliding around. The tan cardboard box (D) has a flip top with tabs for securing the lid. The top of the lid shows a red and black graphic of the PolyStrip tool with "Raychem  /  PolyStrip (TM)  /  Wire Stripper" printed in red and black font at upper right. "PolyStrip (TM) Wire Stripper" is printed on all four sides of the box. "No. 959001" appears on the sides of the box, and additional text on the back reads, "Strips twisted pairs and ribbon cables  /  Can't nick or cut conductor  /  No adjustment for wire size or type."
Raychemer John Deus notes, "This stripper had specially formulated Raychem plastic stripper blades instead of the usual "gauge specific" steel blades in a standard stripper. The plastic blades were harder than the insulation on the wire but not as hard as the copper conductor in the wire. The blades would cut through the insulation, but they would not cut or scratch the copper conductor as the stripper pulled off a slug of insulation. This feature allowed the user of the Polystrip Wire Stripper to strip insulation off wires without having to align a specific wire gauge with a gauge specific slot located in conventional steel blade wire strippers."
