The Greenlee IEP-UDP (52087378) Underground Bushing Probe Adapter is suitable for use with TAG-200 and TAG-200MR Voltage Detectors; it can also be used with the TAG-5000 Wireless Phaser Set. The IEP-UDP Adapter attaches to the ASP-15/25 Underground Bushing Probe (sold separately), which is designed for direct insertion into exposed 15 or 25kV loadbreak bushings. The adapter consequently allows the ASP-15/25 Probe to be installed on the TAG detector or phaser.
