IDEAL Industries 30-852 Wing-Nut® Wire Connector, Model 452® Red, Barrel of 25,000

The red Model 452 Wing-Nut covers the widest range in IDEAL's twist-on line: from two #18 conductors up to four #10. The live-action spring grips small combinations and expands as you add larger conductors, so one bin of red wing-nuts covers most branch-circuit splices instead of stocking several colors.

Yes. The 452 is removable and can be reused on the same size combination or a larger one, which matters on service and troubleshooting work where you open a box, add a conductor, and close it back up. The contoured wing gives enough leverage to back it off by hand without pliers.

The wing is leverage. A smooth cap relies on finger grip, which falls off fast when you are splicing four #10s or working overhead in a ceiling box. The Wing-Nut's contoured wing lets you put real torque on every twist, and the copolymer shell expands for progressive tightening as the spring bites. For high-count splices and large conductors that is the difference between a tight connection and one that backs off.

Part 30-852 is a bulk barrel of 25,000 red Model 452 Wing-Nut connectors. That is a volume pack built for a shop crib, a prefab bench, or a multi-family rough-in where crews draw from a central supply, not a jobsite box quantity.

It will work, but it is the bottom of the 452's range, which starts at two #18. If nearly all your splices are small low-voltage or fixture-wire pairs, a smaller connector in the line is the better match and you get more connectors per dollar of shelf space. The red 452 earns its place where splice counts and conductor sizes vary, up to four #10.

The 452 uses a copolymer shell over a live-action square-wire style spring. The shell is the part that expands as the connector is driven down, which is what gives the progressive tightening rather than a hard stop.
