Product Spotlight: Thomas & Betts Liquidtight Fittings

The new generation of Quick-Connect™ Liquidtight Fittings from Thomas & Betts install up to three times faster than traditional liquidtight fittings.  T&B’s innovative two step push-in technology with a captive sealing ring makes this new line installation-ready — just push and tighten avoiding multiple steps and multiple parts. The new push-in technology is ideally suited for high-volume OEM applications and is compatible with both UL and UA type liquidtight.

In most electrical installations, critical electrical components are protected by a NEMA rated enclosure. These enclosures are like a fort, protecting the castle from any damage or exterior threats. Fittings play a key role in preventing liquids and dust from penetrating the enclosure and maintaining its appropriate NEMA rating.

The T&B Liquidtight fitting line is the end-all for liquidtight and dust-tight connections. You benefit from their expertise and the integrity that their liquidtight and dust-tight connections offer.  Fittings are available for a variety of conduit systems as well as portable cord.

T&B fittings and cable protection systems are made to the highest quality standards and can be specified to meet any customer requirements. If you need it a certain way, they can make it work for you.

Not only do T&B fittings meet the highest standards, but they also offer the largest and most technologically advanced liquidtight fittings in the industry.

Here is a quick overview on the materials and features of the T&B Liquidtight Fittings:

Available materials: Steel, Stainless Steel, Aluminum and non-metallic (PVC, Nylon and Thermoplatics)

See how T&B’s Quick-Connect™ Liquidtight Fittings install up to 3x faster:


No Moisture Pooling: The distinctive pumpkin-like (perfect for Halloween) appearance and unique gland nut on T&B Liquidtight fittings deflects water away from the connector and prevents pooling.

Double-Beveled Sealing: T&B Liquidtight fittings feature unique sealing mechanisms made from high-temperature rated thermoplastic in a distinctive blue coloring. The foolproof design prevents them from accidentally being installed backwards, and therefore, not as secure of a seal.

Infinitely Adjustable: You will save time and money with revolver grounding fittings that use an infinitely adjustable rotating ground lug.

Product Spotlight: Thomas & Betts Dragon Tooth Insulation Piercing Connectors

Now you might read that headline and think to yourself, “French Gerleman has gone mad. Why on earth are they talking about Dragon’s teeth?” We haven’t completely gone crazy, but we are in love with Thomas & Betts newest product, the Dragon Tooth Insulation Piercing Connectors. In this blog, we will take a closer look at what it is and how it can help you. Let us dive right in!

With the Dragon Tooth, you can splice, tap and terminate magnet wire quickly and easily, without any problems. Tough, high temperature insulation on magnet wire that is used by electrical motor and transformer manufactures can create problems in splicing and termination. The durability of magnet wire insulation, while great, the process of removing the insulation by chemical stripping and/or mechanical means can be toxic, time consuming, and a safety concern. That’s where Thomas & Betts came in with a solution.

The Dragon Tooth eliminates the need for chemical stripping and other methods of removing the insulation. That sounds pretty amazing, right? It gets even better. There are no special operator skills needed. The connector and matching tooling do the entire job.

Thomas & Betts Dragon Tooth connectors and installation tools are designed to splice, tap and terminate magnet wire from 32 AWG to 460,000 CMA copper and from 20 AWG to 460,000 CMA aluminum conductors in motor and transformer applications. It can penetrate the insulation and oxide layers to make electrical contact on magnet wiring, with the result being permanent, low-resistance electrical connections that are capable of maintaining contact integrity throughout the life of the connection.

Here are a few additional highlights on the connectors:

  • Made of copper alloy, tin plated, with teeth on the inner surface
  • Splices and taps have an open side enabling easy access to wire and making internal coil tapping possible
  • For aluminum to copper, aluminum to aluminum or copper to copper magnet wire connections
  • Supplied with bolt holes to accommodate No. 6 through 1/2″ studs and includes male and female .250 x .032″ disconnects
  • Splices and fork terminals accommodate wire sizes 24 AWG to 12 AWG in a variety of combinations, including combining magnet wire with stripped wire lead. For solid or stranded wire #20 to #4/0 AWG
  • Larger connectors accommodate circular mil range from 50,000 to 460,000 cm
  • Connector and matching tooling do the entire job

An electrically sound, low-resistance connection is established as a result of the combination of high-pressure at the edges of the teeth and the sliding action between the teeth and the conductor. The open barrel design permits midspan splicing and tapping.

For more information on the Dragon Tooth Insulation Piercing Connectors or how to select a connector, you can download the T&B Dragon Tooth PDF. Or, contact your Account Manager today to learn more! You’ll be saying, “how have I gone this long without Dragon Tooth?”

Product Spotlight: 5 SQUARE® Box from Thomas & Betts

Thomas & Betts has introduced a new line of 5-inch square boxes ideal for low voltage cabling systems and alarm devices.  The new 5 SQUARE® Boxes more than double the cubic-inch capacity of a standard 4″-square deep box, making it faster and easier to route wiring and make terminations in the box.

The 5 SQUARE® Telecommunication Box supports copper CAT5e, CAT6, CAT6A, CAT7, CAT7A and fiber optic cables as well as expected future generations of cables. The boxes include cable management posts to ensure minimum bend radius requirements for high speed data cables and enough interior volume to properly store the slack cable loop.

Avoid the hazards of ground faults and short circuits in fire alarm systems with the 5 SQUARE® Fire Signal Box. Its increased size and space added around the perimeter of an appliance helps to prevent ground faults and short circuits.

The 5 SQUARE® Boxes can save contractors up to 50% in labor costs. By storing the recommended slack loop of communications cabling in the box instead of in a closet or drop ceiling, terminating cables at the box becomes a job for a single technician, eliminating the need for a second technician to access the drop ceiling space where the cable loop is typically stored.

In addition to labor savings, our 5 SQUARE® Boxes provide equipment savings. Compared to standard electrical boxes, the larger size of 5 SQUARE® Boxes enables more circuits and zones to be pulled through, which can reduce conduit and installation costs.

Key features:

  • Twice the volume as standard electrical boxesTnB_SteelCity_5SquareBox
  • Integrated cable management posts prevent kinked and over-bent cables
  • Save up to 50% in labor, increase profits
  • Eliminate the need to remove ceiling tiles to access the slack cable loop, preventing damage and debris
  • Eliminate troubleshooting time and costs
  • Fully upgradeable system
  • Available in red powder-coat finish or zinc-galvanized


Ask your French Gerleman representative for information on how the Thomas & Betts 5 SQUARE® Box can help save you labor and material on your next project.

Featured Product: Thomas & Betts – Blackburn® Hex-Flex® Die System

The growing popularity of flexible-conductor cable, commonly referred to as flex cable, has created challenges and headaches for installers.

Due to the nature of flexible conductors, in certain applications, the traditional hex-style crimp leaves the connection vulnerable to a reduction in pull-out ratings. The indent-style crimp works better than the hex-style crimp, but creates the same problem on flex cable as it does on code cable — lack of ability to inspect for a proper crimp.



Thomas & Betts engineers solved this dilemma by developing a solution that brings the best of both worlds to crimping flex cable —Color-Keyed® HEX-FLEX™ crimp dies. The HEX-FLEX™ crimp uses a hex-shaped upper die to create an inspectable, verifiable, embossed hex crimp on the top side of the connector, with an indenter as the lower die to create an indent crimp with superior pull-out resistance on the bottom of the connector.

A Hex-Flex connection is quick with four easy steps. And each crimp takes less than a minute.


  • Unique dies provide a high-performance crimp on flex cables that can be inspected and verified
  • Can be used on flex cable as well as code wire (consult accompanying chart for proper die and tool selection)
  • Creates a hex-style crimp on the top and an indent-style crimp on the bottom — in one easy step
  • Color-coded for easy matching with Color-Keyed® lugs and splices to eliminate costly installation errors
  • Die-code embossed on connection for easy inspection and verification
  • Full range of sizes available to cover flex conductor sizes M through K
  • Fit most existing 6- and 14-ton T&B compression tools, as well as 15-ton tools with 15500-TB adapter — no additional tool investment required
  • Dies made from high-carbon tool steel with black oxide plating for durability, corrosion resistance and long service life
  • Creates a UL Listed, CSA Certified connection when used on Color-Keyed® compression connectors with flex/24 plus classes B, C, G, H, I, K and M


This video demonstrates the simple, four-step process to make a UL Listed / CSA Certified connection using the Blackburn® HEX-FLEX® Die System, for a high-quality connection at a low installed cost.
