Louvers Diffuse the Air in 2 Directions

Grate Style

(aka Eggcrate, Nautical Hatching)

This is an Excellent Design to Help Maximize Air Flow.

Shaker Syle

Linear Slats are Parallel to the SHORT Dimnension, Straight Up Without Angle.

Linear Style

Linear Slats are Parallel to the LONG Dimension, Straight Up without Angle.

Diamond Grid

Similar to the Grate Style, Allows for Maximum Air Flow with Grid Angled for a Diamond Shape. This Style is ONLY Available in Custom Orders as it is More Laborious to Produce. Please Allow 4-6 Weeks for this Style.

Louver Style

Louvers are Slanted, Angled in 1 or More Directions to Direct Air Flow.

1 – Way Louvers can be Made Parallel to the Long or Short Dimension Per Request. Typically these are Parallel to the Long Dimension.


3-Way Louvers

These can be designed to direct your air flow however, you specify. Ex. 70% direct in the middle, 15% left & 15% right. Let us know what your needs are for this situation.

4-Way Louvers

You can tell us which way you need your louvers to direct you air flow.

Plantation Shutter Louver Style / Dado Louvers of Up To 2″ Deep

This Custom Upgrade adds up to 2″ depth, appearing like a plantation shutter type louver. These can be spaced even further apart for greater air flow.

5/4 Depth


Laser Style

Laser Designs have a multitude of options. You can use one of our stocked designs, or one of your own. We have replicated business logos, fraternities, even wildlife designs.

Laser designs are etched into sheets of 1/4″ thickness, so these will not be load bearing in floor situations or areas that may be bumped with feet often.

Damper Options for Supply Vents

Available for Standard Size Supply Vents

Our Supply Vents do not automatically come with dampers, as we have found most of our professionals such as architects, designers and contractors do not prefer to use dampers. We do carry the dampers as an option for many sizes.

If you are interested in dampers, they must be ordered at the time you place your vent order, not after the fact, as we have to change the construction of your vent piece to make it fit and install properly.

For more information see our Damper and Air Filter Learning Page Here.


Air Filter Package Options:

If you have an air filter behind your vent’s grille, we have a couple options to help you hold this filter in place.

For more information see our Damper and Air Filter Learning Page Here.

If you have an Air Filter behind your grille you can either choose to have Filter Brackets or the Air Filter Assembly Package.

Frame, Hinge & Clasp Assembly Package!

Here we add the surrounding framework around the vent, attach the hinge & clasp so you can easily open the vent for access, as well as use a nylon fastener to open and close. We use this white nylon or plastic clasp as we found the metal ones would scratch the vent surface, causing obvious wear on painted pieces especially. We will also install filter brackets on the back of your grille to hold your filter in place.

Filter Brackets on the back can hold either a 1″ or a 2″ filter size. Let us know your filter size at the time you place your order. We automatically use brackets for a 1″ filter.


(also known as: Surface Mount / Drop In)

has Rounded Leading Edges, Sits Approximately 1/4″ Proud / Atop of Surface.

For a 4 x 10″ duct opening, the Vent will have an Overall Size of 5.75 x 11.75.”

See the Custom Quote Center or Call us for Custom Lip/Flange size to your Overall sizing. Our standard flange/lip will be 7/8″ on each side. If you are Fitting into a Tight Space or Against an Obstruction, such as Needing a Flush Cut Against Molding, Floor, etc. let us know so we can make the necessary modifications.

Countersink Screw Holes may also be added for lip/flange sizes of a minimum of 7/8″ each side. These are pre-drilled holes that allow your screw to lay flush with the vent surface.


Surface / Flush Mount

is Made to Fit Flush within Your Surface. You will Need to Know Your Surface Thickness as well as the Duct Opening Size.

This Fit Allows a Mimimum of 1/2″ Solid Border on ALL 4 Sides of Your Duct Opening.

This Style is Favored by Leading Designers, Architects, and Industrial Professionals.
