About Stair Tread Covers and Nosing
More
Stair Tread Covers
Protect stairs from wear or provide a new stair surface on worn stairs. Covers fit square-nose concrete and wood stairs.
Styles A and B are oil- and chemical-resistant vinyl. To install, use construction adhesive (sold separately).
For technical drawings and 3-D models, click on a part number.
Traction Floor Plates
Add permanent slip resistance to floors, ramps, stairs, and docks with these solid plates.
Plates with grit have an abrasive-coated surface for increased traction and durability.
Fiberglass and UHMW plates are nonconductive, corrosion resistant, and nonmagnetic. UHMW plates are more UV resistant than fiberglass. Cut to size using a circular saw with carbide-tipped blade.

Enclosure Vents
Attach these vents to the top or side of sealed enclosures, so air can flow through to equalize internal and external temperature and pressure.
Style A and B vents have an angled outlet, which helps keep rain, snow, and debris from entering the vent and the enclosure.
Style C vents have mounting holes for attaching a fan (not included), so you can increase the amount of air that flows through your enclosure.
Style D vents are protected from rain and water, so you can use them in washdown and other wet environments.

Wet Location Breather Vents
These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out. They have a PTFE seal that stands up to oil and corrosion and allows airflow in, reducing the risk of the seal failing due to changes in air pressure. They also minimize condensation that may rust internal electronic components. Made of polycarbonate, these vents withstand corrosion and UV rays.

Corrosion-Resistant Washdown Threaded Breather Vents
Rated NEMA 4X, these vents provide protection from washdowns, corrosion, and power jets of water. Use them to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.
For technical drawings and 3-D models, click on a part number.
Submersible Threaded Breather Vents
Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures. All have a hydrophobic and oleophobic filter membrane that blocks moisture and contamination from particle buildup.
Nylon vents don’t conduct electricity, making them a good choice for most environments.
Polycarbonate vents don’t conduct electricity and withstand UV rays better than nylon vents, so they won’t break down as quickly in outdoor applications. All have a mounting nut for a secure connection in threaded as well as through holes.

Submersible Snap-In Breather Vents
No threaded hole or tools needed—snap these vents into enclosures with a maximum 1/8” panel thickness to let airflow in and keep water out even when submerged. Use them to maintain consistent pressure inside your enclosure as temperatures change. These vents have a pressure compensating seal that prevents pressure buildup. They also have an acrylic filter that resists dust, water, and oil.
