Introducing

The Corwin Rafter Vent™

   For the first time in the building industry, the area's above and below the skylights, valleys, chimneys, and hip roofs can be vented properly, eliminating mold, hot spots, and water back-up.

   The Corwin Rafter Vent is used to ventilate unventilated areas of your roof.  Using the CRV eliminates the need for drilling holes in the rafter or truss trying to get the air to move thru a particular area, which in fact only weakens the structure.

   The Corwin Rafter Vent is 1½" wide x 2" deep x 48" long and becomes an integral part of the rafter or truss when screwed in properly.

The Corwin Rafter Vent™ is the solution.
