Supports selected solid or stranded conductor combinations from 22 AWG up to 8 AWG.
Secure Twist-On Connection
The fastening design grips conductors and helps the splice remain stable under normal vibration.
Outdoor Application Focus
For landscape lighting, irrigation controls and other outdoor connections exposed to moisture.
Compact Connector Body
The 38 × 27.2 × 24 mm body fits practical junction and enclosure layouts.
OEM and Bulk Supply
