In 1914, William Marr invented the
world’s first pressure type wire
connector. Since then, Marrette
®
connectors have become synonymous
with ”best quality wire connector“.
Easy to install and comfortable in the
hand, they are indispensable to
electricians. And now they’re available
as key components of Thomas &
Betts’ Electricians’ Supplies product
line. This is very good news for your
fingers.
How good are they?
The first thing you’ll notice about T&B
Marrette wire connectors is that they
come in a variety of types and styles,
making it easy for you to identify wire
size at a glance.
Feature for feature here’s what makes
Marrette connectors significantly
better than other connectors.
• Marrette connectors are the ONLY
wire connector to offer a non-
winged, variable-volume live-action
spring in the connector. The spring
expands to receive the conductors,
rather than crushing them together,
as typical non-winged competitors
do.
• They can handle a broader range of
wire connection combinations.
• They’re coated with 100% pure
copper, which reduces the corrosion
common to tin and zinc-coated
products.
• Marrette connectors’ “finger friendly”
design offers a truer grip for less
hand fatigue during repeated use.
• They are the ONLY red non-winged
connector that is U.L. listed for a
pair of #8 awg wires.
• The high-grade polypropylene outer
shell prevents “blooming” or
“blossoming” of the connector side-
wall. The outer shell maintains a
constant moisture level, reducing the
likelihood of the connector becoming
dry, brittle, and subsequently
cracked due to extreme heat or cold.
