Thomas Betts ADR2 Square Ring Terminal 14 to 2 Awg

Product Description

The THOMAS BETTS ADR2 is a non-insulated square ring terminal designed for compression connections in electrical wiring applications. It accepts wire sizes from 14 to 2 AWG and fits a 1/4-inch stud. The contact is aluminum with a TiN (titanium nitride) plating for reliable conductivity and corrosion resistance. The terminal measures 1-5/32 inches in overall length and 1/2 inch in ring width, with a material thickness of 7/64 inch. Licensed electricians and trained electrical installers use this terminal in panel wiring, grounding, and branch circuit terminations where a secure, permanent crimp connection is required.

The ADR2 suits residential and light commercial electrical installations where non-insulated ring terminals are preferred for lug-style terminations. It is commonly used in junction boxes, electrical panels, and equipment connections that require a 1/4-inch stud mount. Its broad AWG range — 14 to 2 — makes it adaptable across a variety of conductor sizes within a single project or service call, reducing the need to stock multiple terminal sizes for common wiring tasks.

• 1/4-inch stud size fits standard lug and terminal strip hardware
• UL Listed (UL File E9809) and CSA Certified; RoHS Compliant

Compatibility

Designed for use with 14 to 2 AWG conductors and 1/4-inch stud hardware in compression-type terminal applications. Consult the THOMAS BETTS ADR2 product data sheet to confirm tool and die compatibility with your crimping equipment before installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit before crimping or terminating any conductors. Use a calibrated compression crimping tool rated for the AWG range and terminal type to ensure a proper mechanical and electrical connection. Do not re-crimp a terminal that has already been compressed onto a conductor.
