Place these grilles in the grid of a drop ceiling.

No additional fittings or collars needed.

A vapor barrier provides moisture protection as these diffusers spread hot or cold air around a room.

Place these diffusers in the grid of a drop ceiling to distribute air evenly throughout your space.

Diffusers come with a collar and damper already in place for simple installation.

Evenly disperse airflow into a room to maintain a consistent temperature throughout the space.

Install onto floor ducts to direct hot and cold air from your HVAC system.

Relieve heat buildup and prevent condensation from forming inside enclosures and other small spaces.

Use these louvers in harsh environments—they won't rust.

Constructed with a thick frame and blades, these louvers have a long service life.

Get an exact fit for your opening by sliding out these louvers to the width you need.

Mount these louvers into openings that are too small for most louvers. They are sized for use in block and brick walls.

Allow air to circulate through doors while maintaining privacy.

These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts.

Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.

Safe for use around flammable and combustible gases, vapors, fibers, and dust, these vents allow air to flow through enclosures to maintain consistent pressure and reduce moisture buildup as temperatures change. They also stand up to washdowns.

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.

These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out.

Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.

Safe for use around hazardous gasses and dust, these vents maintain steady pressure and prevent moisture buildup from temperature changes inside enclosures.

Safe for use around flammable and combustible gases, vapors, fibers, and dust, these drains let moisture buildup from temperature changes inside enclosures drip out to keep electronics dry.

Often used for electric-to-gas conversions and renovations, these exhausters allow gas- or oil-fired equipment to be vented through a sidewall rather than a chimney.
