ReadyMax PlugsPockets ensure compliance and convenience for every employee on the job site by providing instant hearing protection on your hard hat or safety vest, installing in seconds with a 3M(R) peel-and-stick adhesive. The PlugsPocket is designed to match the reflective strips on a safety vest. Durable push-button retractors have a heavy duty spring and clutch assembly which provides positive locking when the tethered earplugs are extended; a strong, coiled spring retracts earplugs into a covered, reflective pocket. The tethered earplugs extend 15" and will not impede head rotation and movement. The PermaPlug Earplugs provide an NRR of 25.
