NO-PEST VENT NPJB 4 in. J Block or Wide-Mount Dual Door Wall Vent in Brown

About This Product

A dryer vent cover that keeps pests out of the exhaust run, holds heat in and asks almost nothing of you afterwards. The dual door design is the point: birds, mice and other pests cannot get past it, and the outer door sets up a vortex that draws extra outside air through, adding lift and flushing lint clear. The result is the highest airflow and cleanest-running vent of the type.

Highlights

• The dual door damper shuts out the draughts that otherwise track back through a dryer vent, and a magnetic retention system stops the doors flapping in gusty weather while sealing tight against insects and rodents
• The dual door design sets up a self-cleaning vortex outside the cover that keeps lint from building up and moves exhaust air efficiently, so clothes dry faster
• No lint-collecting screen, which is where obstruction and fire risk usually come from – screens also violate international building code
• Made in Zeeland, Michigan from American plastic resin with high UV resistance; the original units are still in service on the apartments they were first fitted to fifteen years ago
• Meets international building codes for a dryer vent cover, and avoids the screen that makes many alternatives a fire hazard
