Selection Guide
Start with the conductor section and AWG range, then compare current and thickness for the selected model. Match the bolt reference and d2 diameter, then check ring width and overall length against available space.
Use a compatible insulated-terminal crimping tool. Confirm strip length, crimp settings, retention and inspection requirements; do not select by insulation color alone.
Applications
Potential uses include equipment wiring, control-panel assemblies and cable harnesses requiring a compatible bolted ring connection. Suitability depends on the approved assembly.
Confirm voltage, temperature, environmental conditions and required approvals for the selected model. These ratings are not specified on the original product page.
Ordering Information
Provide the complete RV model number, conductor size, bolt or stud reference, application and order quantity. Include sample, packaging and inspection requirements.
