How to Calculate Net Free Area

Rounded attic vents are custom made when purchased to match the style and kind of install for the project. By making these wall vents so personalized and specific, most installs take less than 5 minutes. No excess cutting, trimming or filling in the opening for the vent to fit.

All louver vents are manufactured with the 4-fold louvers locking onto a rail for extended life and strength of the vent. No facing or exposed pop rivets to pop out. Louvers stand straight and true.

Quick Reference for Round Vent Ordering

Measuring is easier than most think.

This vent only requires the width and the height.

How to Measure

"Opening size" just means the measures were of the vent hole in the wall. For this, we will reduce your measures 1/4 inch dimensionally to ensure a good fit.

"Tip to tip" is if the vent size itself is to be the measures ordered with no reductions.

A "boxed base" is squared and boxed for a wall install.

The "roof pitch angle base" is in reference to the vent sitting directly onto the roof metal or shingles. For this, type the pitch into the comments box and we will pre-set the base at that angle. The only place the pitch will be applied is the bottom louver.

Vent Depth

The depth of the Round vent is as shown in the changing pictures. So, just how thick the vent will be or how far it will protrude into the gable wall.

Flange / Nail Fin

Offering all 4 flange mounting styles with a straight curvature. No "pie crust" or "armadillo" face trim here.


If the Circle vent will be painted or is matching a painted home color, enter primed white into the "color" box. Otherwise, enter the trim coil manufacturer and the color name and the finish.


Aluminum screen for the back of the vent is a bug screen for crawling and flying insects.

The grasshoppers and wasps can chew through the fiberglass screen.

The non vented has a solid metal back to block all air and water so it is decorative only.

And the half inch wire mesh option automatically comes with aluminum screen to provide both bug and larger 4 legged critter protection (squirrels, raccoons, roof rats, etc.).


Shipping small products will be via UPS Ground or UPS Oversize Ground in wooden crates to ensure the product safety during shipping.

Larger aluminum products ship with SAIA Freight. These too are packaged in wooden crates. Freight items require a commercial delivery address or will be delivered to the nearest freight hub for individual pick up. Residential delivery is not available to all addresses.

If any product ordered is over 48 inches, call 901.281.2887 to find out if it will ship ground or freight.

Most items ship within 3 weeks. But due to some current shipping delays, always order products a month or more in advance to ensure delivery before needed. Stocking many of the commonly ordered colors speeds up the lead time drastically, but not on all.
