How to Measure a Louver Gable Vent Signature Series

 How to measure a louver gable vent.

Triangle:

Fisrt find your base length across the bottom of the wall opening.  These vents are measured by the opening size.  Second, measure the height of the opening at the center point.  Some triangle gable vents are off center.  If so, then also mark the highest point on the bottom of the opening and measure across to that point from both sides.  This will tell us where the center height should be.  The vent we manufacture will be 1/2" shorter in width and height to ensure a good fit.  Only use the opening measures.  Do not include for flange.  Flange is added to these measures during production.

If you choose to not remove your old louvered gable vent before your new one arrives, you can measure from inside your attic for the opening size.  Or follow the measure lines on the picture above.  The height will be in the center below the top flange to the bottom on top of the bottom louver.  The width will be on top of the bottom louver and from the inside corners of the flange.  You can also use the "comments box" when ordering to specify if your measures are "tip to tip" (the measure you want) or "opening size" (we will deduct 1/2" to ensure a good fit).  If you do not specify, we will make the vent as opening size to prevent oversizing.

Square or rectangle:

A square vent measures the same.  Use the height and width of the opening to order a square louver vent.  We will deduct 1/2" from the over all measures for manufacturing the vent.

 

Round:

Sounds tough, but it is simple.  Just measure the height and width of the opening and we will do the rest in making the vent round.  Again, we deduct 1/2" to make your install easier.

 

Contractor grade vents:

These are the only vents that measure the same as the measures you order.  If you orer a 12 x 18, it will fit an opening of 12 1/2" x 18 1/2".
