Catamount® Wire Connectors
In 1914, William Marr invented the world’s first pressure-type wire
connector. Since then, these connectors have become synonymous
with “best quality wire connectors.” Easy to install and comfortable in the
hand, they are indispensable to electricians. And now they’re available as
key components of the Catamount
for your fingers.

How good are they?
The first thing you’ll notice about Catamount® 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 Catamount
better than other connectors.

connectors significantly
• Catamount® 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.
Identification & Supplies — Catamount
• Catamount® 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 UL Listed for a pair of #8 AWG wires.

• The high-grade polypropylene outer shell prevents
“blooming” or “blossoming” of the connector sidewall.
The outer shell maintains a constant moisture level,
reducing the likelihood of the connector becoming dry,
brittle to extreme heat or cold.

Catamount® Set-Screw Vibration-Proof/Visible Connection
The Catamount® Set Screw is a two-piece, pressure-type connector
featuring a solid brass insert with a screw-on insulating cap. It’s the perfect
choice when changing a motor, adding a circuit, conducting instrument
testing or simply lashing-up temporary wiring.

• Made of rugged, phenolic material and 150° C-rated.
• Insulator cap locks securely in place to safeguard against
accidental loosening in high-vibration applications.
Brass Insert
• Choice of slot or Robertson set screw. When tightening
into the insert, provides a solid pressure-type connection
on all approved wire combinations.
• No need to “re-strip” wires when rewiring. Simply
loosen set screw to remove non-twisted wires.
• CSA (LR6591), UL (424H) — approved
for circuits up to 600V and lighting
fixtures and signs up to 1,000V.
• Convenient packaging — sized right
and jobsite ready!
