Alside Laguna Blue PVC coated aluminum circular gable vent measuring 30 x 30.
The 30 x 30 is the vent itself.
When adding the J channel flange around the face, now the outer visual will be 32 x 32.
The rear of the J channel is 2 1/2 inches beyond the vent and will not be visible after the vinyl siding installation.
But the wider rear flange creates excellent water protection.

Round air exhaust vents
Most aluminum vents from other manufacturers have a crinkled face plate for making it round.
These have a smooth trim face for a neater appearance.

With a full open receiver pocket, it gives good coverage of sdiing ends.
Thicker vents can be customized with an even deeper J channel for insulated siding, Hardie Plank and even CertainTeed concrete siding.

Each louver or slat is locked onto a rail hidden behind the face trim.
So, even a vent as thin as an inch will be sturdy even before install.

Circular vents over 20 inches round will have a seam on the face trim.
This is barely visible before install and usually not after.
This seam is locked together just like the J flange for a stronger, better louver vent.
