3M 7100178151 | 1411-XR-1H Disk Marker

Description

The 3M 7100178151 (Disk Marker 1411‑XR‑1H) is a passive locator disk designed to securely mark underground, flush‑mounted utilities like telephone handholes. Encased in a water‑resistant polyethylene shell, it ensures durable performance even when facilities become buried under backfill, debris, or vegetation. Providing reliable signal return up to 5 ft (~1.5 m), this non‑metallic lid marker supports accurate location without external power. A core component in 3M passive locator disk systems, it enables precise mapping and maintenance of buried assets.

Product Features and Benefits

Passive Antenna for Accurate Utility Location

Designed to reliably respond to an RF signal via a utility locator, the disk marker supports consistent detection under non‑metallic lids up to 5 ft range.

Flush-Mount Compatibility for Surface Enclosures

Mounts easily to the underside of plastic or composite covers over utility vaults—ideal for disk marker for buried utilities applications without obstructing lids.

Orange Water-Resistant Poly Shell for Durability

Encased in bright orange polyethylene, the unit withstands temperature extremes of –4 to 122 °F and resists moisture ingress for long-term field use.

No Power or Batteries Required

As a respirator battery charging unit—sorry, mistaken reference—this unit requires no power source, ensuring low maintenance and reliability underground. Passive design avoids potential failure due to battery depletion.
