The 3M Peltor Welding Helmet Earmuff H505B features a low-profile design that fits comfortably under most welding helmets, as well as a semi-soft cup surface that minimizes scratch sound transmission. With a two-point suspension for balanced pressure distribution, this advanced earmuff delivers the comfortable protection that professionals need in a wide range of welding environments.
The H505B earmuff helps reduce exposure to the loud noises associated with welding, cutting or grinding. Its slim design allows it to fit under most welding helmets, particularly 3M Speedglas 9100 Series Helmets.
Many unique features make the H505B earmuff the right choice for welders. And with the available Hygiene Kit, workers can replace sealing cushions and earcup inserts as needed to help them stay comfortable and protected on the job.
