Grid Style Models

Insert Model
For applications in floors of any thickness, walls or ceilings, when maximum air flow is desired. The Insert Model has a self-rimming, eased lip 1/4” thick and 1” wide. Fluted dowels secure each web to the 1-1/2” wide side rails and end pieces. Specify the exact opening size when ordering.

Flush Model
For maximum air flow, use the traditional grid style with 3/8" wide webs to which 1 1/2" rails and ends are added and fully doweled to each web member.  Frames are cut from 1" rabbeted stock.  The frame is glued and blind-nailed to the subfloor and the flooring is fitted to it.  When finishing is complete, the vent is placed in the frame.
