3M “PERFORMANCE PLUS” CONNECTORS
BROAD WIRE RANGE = INVENTORY SAVINGS
Because of their increased wire range, just three “Performance
+
” Wire Connectors
handle the work of eight standard connectors. O/B
+
replaces the orange, blue, gray and
yellow wire connectors. R/Y
+
or T/R
+
replace red, tan and yellow connectors. B/G
+
covers both the large blue and gray connectors. This simplifies selection of the right
connector for a wide range of wiring jobs. There’s also less inventory to manage, and a
better chance you’ll have the connectors you need to do every job.
In addition, they are exceptionally easy to handle. Their one-of-a-kind design
incorporates a flexible skirt and a rigid top. The flexible skirt covers over-strips yet
conforms to whatever space is available in a box.
This exclusive feature allows Performance Plus connectors to provide maximum
protection and fit inside even the most crowded electrical boxes.
The rounded wings on the rigid top make 3M wire connectors
exceptionally easy to handle. Twisting the connector—on or off—is
easier than ever. That means fast installation and less wear and tear on
your fingers.
Inside, the unique spring grips quickly, turns on fast and expands to
accept a wide range of wire sizes. It bites into conductors for solid, secure
connections. The 3M “plus” connectors also feature a large, funnel-shaped
throat design. The connectors meet UL max-fill requirements. All Performance Plus wire
combinations are UL listed for 600 volts on copper wire.
