How to Calculate Net Free Area
Measuring is easier than most think.
Why not order by the vent pitch? Because if the framer was off the line when cutting the rafters, the entire roof line will not be an 8/12 pitch, but rather an 8.2 pitch or a 7.8 pitch. Just a fraction on a rafter cut with a saw can change the measure of the vent by several inches.
How to Measure
"Opening size" just means the measures were of the hole in the wall. For this, we will reduce your measures 1/4 inch dimensionally to ensure a good fit. Do not deduct measures yourself. They will not be accurate.
"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 depth of the 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.
Offering all 4 mounting styles.
If the half left triangle 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 wire mesh option automatically comes with aluminum screen to provide both bug and larger 4 legged critter protection (squirrels, raccoons, roof rats).

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.
