MV4S 4-Way Diffuser Grille for 4/5/6" Duct

This is engineered well and adaptable to various heights. It is perfect for drop ceiling tile installation. Very easy to install and solves the problem of connecting to existing rectangular duct work since you can use flexible round connecting tubing (buy that separately). The four way diffuser ensures soft distribution of air flow. The color works great with our Armstrong "Sahara" ceiling tiles - virtually disappears in the ceiling. Love the baffle closure which is so important to regulate temps when you don't have zoned HVAC in the basement.

This grille is mostly meant for drywall applications (it has wings to tighten down once you cut opening in drywall). Then you simply tape on duct and you are good to go! Comes with a "key" to adjust diffuser. Nice and sturdy as well, and having the ability to use 3 different sized duct makes it a no-brainer!

These grilles can be cut to fit the different sizes of system hose or tube. Easy installation.

These were easy to install and look nice, we used them for our A/C ducts. Perfect that we can close them in the winter to avoid cold air coming through or warm air escaping.

Easy to install in ceiling and looks and works good.

Have not installed yet, but it is exactly what I wanted. Repeat customer. Thanks

I like the price. Easy to install. They look great. Diffuse heat . I really wish winter would go away.
