Detectable Foam Earplugs

Howard Leight LT-30 detectable foam earplugs are designed for workers in process industries where automated inspection technology requires visual and metal-scan detection. The nonferrous metal grommet ensures the plugs can be identified by scanning equipment if they enter the production line. Bright orange and blue coloring provides high visual contrast for easy spotting.

32 dB NRR and Low-Pressure Fit

A noise reduction rating of 32 dB delivers high attenuation for loud industrial environments. Low-pressure polyurethane foam expands gently to match the wearer's ear canal without creating excessive pressure. The contoured T shape assists with quick insertion and removal during shift changes.

Corded Design with Brass Grommet

Each pair is corded to prevent loss and keep plugs accessible around the neck when not in use. The brass grommet embedded in the stem provides the metal-detectable property required by food and pharmaceutical safety protocols. Universal sizing accommodates a wide range of ear canal shapes.

Questions about this item

Will the 32 dB NRR foam plugs fit comfortably under my existing earmuffs without breaking the seal?

The low-pressure polyurethane foam expands gently to fill the ear canal, and the contoured T shape keeps bulk low so the plugs sit flush under most over-the-ear muffs without lifting the cushions.

How can I confirm the metal grommet is still detectable after a shift of heavy vibration?

The nonferrous brass grommet is moulded into each plug; a quick pass with the plant metal detector or visual check for the bright orange and blue colouring confirms the plug is intact and detectable.

Does the box include a dispenser or do I need to order a separate wall bracket for the LT-30?

The LT-30 is supplied as corded pairs in a bulk pack; no dispenser or bracket is included, so a compatible wall-mounted dispenser must be purchased separately if required.
