Large, Custom Wood Vents!!

How big do you  need?

From time to time, customers will have exceptionally large openings they need a wood vent for.  Sometimes these are large returns.  Sometimes these are going to be openings in custom cabinets or media centers.  Other customers have just had large openings allowing air to circulate between floors of a house.  Currently we are working on large units to be used as stair risers in Manhattan.

Generally speaking, the largest one piece vent we can make is 48" duct opening.  However, we can work with your vents to give as seamless a look as possible.

Local Customer with 129 1/2" duct opening!!!

A local customer came to our shop, and told us she had a duct over 10' long she wanted a wood vent for.  At first we were confused, but after seeing a picture we realized it was true.  No problem we said!  Take a look at how we did the joints to appear totally seamless.  Three pieces of wood have been assembled to look like one solid wood vent.

Large Return Vent for Dune Road in Southampton - Eggcrate Style

For a custom home on Dune Rd, the builder wanted the eggcrate style vents to be flush to the wall, and made with all even sized holes.  We worked with him to provide the perfect sizing.  One vent had a duct opening of 60", and we were able to make the two pieces butt together seamlessly.  Once this vent was painted the homeowner couldn't believe his large return was made out of two vents.

We specialize in custom projects!  Feel free to call us at
