Ideal Industries 3-2121 Vinyl Insulated Ring Terminal 22-18 Awg

Product Description

The IDEAL INDUSTRIES 3-2121 is a vinyl insulated ring terminal designed for secure, lasting wire-to-stud connections in electrical systems. Rated for 22-18 AWG wire, it accepts a No. 6 stud and features a color-coded vinyl sleeve for quick wire-gauge identification during installation. Ring terminals in this class are installed by licensed electricians and experienced technicians on control wiring, panel work, and general low-voltage circuit terminations. The vinyl insulation protects the crimp joint from abrasion and incidental contact. Sold in a box of 25, making them practical for service vans and shop stock.

These terminals are suited for residential and light commercial electrical work where a secure, insulated ring connection is required. Typical applications include control panel wiring, appliance terminations, HVAC low-voltage circuits, and general-purpose branch circuit work. The No. 6 stud size fits a wide range of terminal blocks, ground lugs, and equipment studs commonly found in the trade. The color-coded sleeve allows technicians to confirm wire gauge compatibility at a glance without measuring.

Key Features
