  • TypeElectrical Connectors
  • CSA and UL listed for code compliance

  • Brazed barrel resists pull-out under load
  • Tin-plated copper ensures low-resistance connection
  • Rated to 347 °F for demanding environments

Electrical Crimp Ring Terminal

This 3M ring terminal accepts 6 AWG copper building wire and provides a crimped connection for 1/4 inch studs. The bare copper barrel with tin finish is rated for 1,000 V and a maximum temperature of 347 degrees F. UL Listed and CSA Certified, it suits panel work, fixtures, luminaires and sign installations. Brazed barrel construction ensures the crimp stays intact under vibration.

Uninsulated Design For Visible Inspection

The terminal has no insulation covering, so every crimp joint remains visible for quality checks. This suits installers who must verify barrel fill and conductor placement before energising a circuit. Buyers who need insulated terminals for accidental-contact protection or colour-coded wire identification should look at insulated alternatives. The bare barrel also lacks a flared entry, so wire strands must be pre-twisted for smooth insertion.

6 AWG Single-Size Crimp Barrel

The barrel inside diameter of 0.25 in and length of 0.39 in accept only 6 AWG conductors. Using a larger or smaller wire gauge will not produce a reliable crimp and voids the UL listing. Confirm the wire size matches exactly before ordering.

Questions about this item

How much current can this 6 AWG terminal carry once it is crimped in a real machine?

The terminal itself is rated for 1,000 V and 347 °F; actual ampacity depends on the 6 AWG conductor you install and the applicable wiring code.

What does the 1/4 in stud size mean for the connection hardware I need?

The tongue has a 0.52 in hole spacing and fits a 1/4 in (6 mm) bolt or stud; use matching hardware to secure the ring.

What are the exact barrel dimensions I need to match my crimp tool?

The barrel inside diameter is 0.25 in and the barrel length is 0.39 in; choose a die set that matches those dimensions for 6 AWG wire.
