Triangle Louvered Gable Vents Signature Series

Do you want to order a triangle gable vent with your measures or order by pitch?

We offer ordering your triangle louvered gable vent by your measures and by the gable vent pitch.  Offering both options, you can order your triangle gable vent the way you want instead of trying to figure out the pitch measure conversion.

Ordering your gable end vent by pitch is pretty easy if you know your roof pitch.  All you need is your gable vent base length measure.  

If you prefer, you can measure your triangle gable vent length across the bottom and the height up the center of the vent.  For this you can use your measures to order your triangle louvered vent.  This option also allows you to order a triangle end vent of an odd size.  Maybe, your roof line is not a perfect pitch.  It could be a pitch and a half.  For a better fitting triangle gable vent, you will want to use your measures to order.

We offer all the common measures of the basic pitches 4/12, 5/12, 6/12, 7/12, 8/12, 9/12, 10/12, 11/12, 12/12, 14/12 and 16/12 triangle gable end vents in one foot incriments.  

The wall opening size is the measure you use to order your triangle gable vent.  Your gable vent will be manufactured 1/2" smaller than your order size to fit the opening.

These are standard opening sizes by width first and height of the common triangle vent sizes.

As you can see, the standard trianglular gable vent sizes are arranged by 1 foot increments.  So your base lengths are standard as follows:

24" gable vent for a 2 foot base length on the triangle

36" gable vent is a 3 foot bottom of the triangle shape

48" gable vent gives a 4 foot length on the trianglular vent

60" gable vent makes for a 5 foot bottom length across the triangle vent

72" gable vent is a 6 foot base for a triangle form

84" gable vent renders 7 foot triangle vent louvered

96" gable vent makes for an 8 foot 3 sided vent 

108" gable vent is reference to a 9 foot vent base triangle

120" gable vent is for a 10 foot gable vent bottom on the triangular form
