Carlon® Fittings Install from Inside or Outside of Electrical Box

New T&B Product Packaged in Reusable Plastic Containers

Carlon® fittings from Thomas & Betts (T&B), a member of the ABB Group, are among the only non-metallic fittings for electrical boxes that can be installed from either the inside or outside of the box.

The new Carlon fittings are UL® Listed and CSA™ certified, and are certified for one or two sheathed cables. Two sheathed cables may be inserted through the fittings either together or one at a time. They are color coded for easy identification: ½-inch size is gray, ¾-inch size is blue.

“Carlon fittings snap easily into knockouts without the need for tools, and hold sheathed cable snugly to prevent movement within the knockout,” said Ralph Donati, product marketing director at T&B. “The contractors who tested them found that enabling installation from the inside or the outside made them easy to use.”

In addition to electrical supply distributors, Carlon fittings are available from retail outlets for homeowners and small electrical contractors. Carlon fittings are packaged in reusable, 20-ounce plastic containers that feature tamper-proof lids, shrink seals and grip indentations on the back. The containers are clearly labeled and can be stacked for display.
