Multi-Position Dielectric Safety Earmuffs | NRR 21dB

Item

Description

The MU-19137 Multi-Position Dielectric Safety Earmuffs are an indispensable asset for utility workers, linemen, and personnel operating in complex environments requiring multiple layers of PPE. The defining feature of this model is its 100% Dielectric construction. By utilizing high-strength, non-conductive polymers instead of metal wires or structural clips, these earmuffs eliminate the risk of electrical conductivity, making them safe for high-voltage power generation and electrical maintenance zones.

Furthermore, the MU-19137 addresses the common challenge of PPE compatibility. The 3-Position Adjustable Headband allows the operator to rotate the supporting band behind their neck or under their chin. This critical flexibility ensures that the earmuffs maintain a secure, noise-blocking seal (NRR 21dB) even when the worker is simultaneously wearing a brimmed hard hat, a welding helmet, or a full-face respirator.

Key Features & PPE Integration

100% Metal-Free (Dielectric): Safe for use in electrical utilities, server rooms, and environments with arcing hazards, protecting the worker from accidental shock.
3-Position Headband Flexibility: Easily shifts to fit over the head, behind the neck, or under the chin, allowing unhindered use of other vital head-borne safety equipment.
Reliable Acoustic Blocking: Delivers an NRR of 21dB (SNR 25dB), perfectly suited for moderate noise environments like landscaping, general manufacturing, and woodworking.
Lightweight Ergonomics: The polymer build reduces total head weight, minimizing neck fatigue for workers who already carry the weight of a hard hat and face shield.
High-Capacity Option Available: For environments requiring extreme noise blocking along with multi-position wear, we offer the MU-19138 variant, scaling protection up to an impressive NRR of 35dB (SNR 22.5dB).

Frequently Asked Questions

Q: Why is it important that these earmuffs are dielectric?

A: Standard earmuffs often use steel wire for the headband to provide clamping force. In an environment with exposed high-voltage wiring, that metal can conduct electricity and cause severe injury. Dielectric earmuffs are built entirely from non-conductive plastics, completely eliminating this hazard.

Q: How does the 3-position headband help workers?

A: When a worker wears a standard hard hat, an over-the-head earmuff band will not fit under the hard hat's suspension webbing. The 3-position design allows the worker to rotate the earmuff band to rest behind the neck, allowing the hard hat to sit securely on the head while still providing necessary hearing protection.
