About Hearing Protection
Earmuffs and earplugs are rated by the Noise Reduction Rating (NRR) guidelines, which are enforced by OSHA.

Square-Head Expansion Plugs
Turn the square head of the plug into the sealing ring to close off pipe openings. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
Tight-Grip Push-In Bumpers
A ridge on the stem provides a tighter grip than other push-in bumpers. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.
Bumpers with a hard and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
Polyurethane bumpers have better abrasion resistance than SBR and plastic bumpers. They won't become brittle and crack when exposed to ozone. They're also nonmarking.

Compressible-Stem Push-In Bumpers
The stem on these bumpers compresses to fit into tight holes. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.
Bumpers with a soft and extra-soft rating offer cushioning. The softer the bumper, the more it cushions.

Floor Drain Plugs
Often used to prevent spills from going down your drain, these plugs resist oil and most chemicals. They are nonabsorbent, washable, and reusable. An eyebolt at the top makes these plugs easy to insert and remove.
Ambient-Noise Canceling Earplugs
Reduce exposure to loud background noise from nearby machinery without blocking out voices. Instead of muffling all sound like other earplugs, these soften sound to enable clear communication. Slide them right into your ear without rolling. Small earplugs fit most women; medium ones fit most men.
Earplugs with a sliding toggle come with six pairs of plugs in three sizes, so you can find the perfect fit for your ear. They let you change the noise reduction rating between 15 dB and 22 dB; slide the toggle with your finger to adjust the hearing protection as needed. These earplugs are good for jobs where you may perform especially loud tasks, such as turning on power tools. Because they have built-in noise filters, you can toggle between ratings while these earplugs are still in your ear—no need to take them out to swap out the filter. Embedded with magnets, they connect together when not in use for easy storage.

Spill-Control Drain Covers
Block grates and manholes to stop liquids from going in, or seal inactive drains to keep odors from leaking out. Wash and reuse these polyurethane covers for multiple jobs—this durable material doesn’t tear easily and won’t degrade in water, oil, or chemicals.
36” wd. × 60” lg. covers are designed to fit over trench-style drains.
