The Perfect Balance Return Air Pathway has a specially designed baffle material to mitigate sound and light. It is easy to install in a door, can be painted if necessary, and is durable with a lifetime guarantee. The RAP Return Air Wall Transfer Grille allows the movement of air from one room to the next, equalizes pressure in the home, dampening sound and light transmission. It comes in five different sizes that are easy to install.

To be featured on BPI's approved Product List, products must meet the appropriate industry standard or efficacy requirement that BPI identifies.
