Klein Tools 60502 Hard Hat Earmuffs, Full Brim Style

The 60502 earmuffs are built to mount on Klein Tools full brim hard hats. The connector and wire arms are matched to that brim style, so treat it as a Klein full brim accessory rather than a universal slot-mount muff. If your crew runs cap-style hats or another brand's shell, this is not the pairing to order.

Noise Reduction Rating is 26 dB when worn on a safety helmet and 27 dB on a cap-style hard hat, rated to ANSI S3.19-1974. That puts it in range for general construction, power tool, and jobsite generator noise. If your site's hearing conservation program specifies a minimum NRR, check that number against 26 dB, since that is the rating that applies on a helmet.

Yes. The connector pivots into three positions: in-use over the ears, stand-by clear of the ears, and a storage position. That is the detail that matters for crews moving in and out of noise all day, since nothing has to be unclipped and set down where it gets lost.

No. The 60502 is not an insulated product, so do not treat it as electrical protection. It is hearing protection only, and the cups are ABS plastic. For linemen and electricians the muff is fine as PPE against noise, but arc and shock protection has to come from rated gear elsewhere.

The wire arms adjust so each worker can set the cup height, and the cups have a spacious interior with soft foam cushions for the acoustic seal. For a shared tool crib or a fleet of hats across a crew, that means one part number covers the crew rather than sizing per person.

Grey with orange accents. For a standardized PPE program that is a high-visibility combination that reads clearly at a distance on a full brim hat, and it is the only color the 60502 is built in, so reorders match what is already on the crew.
