Launstein Hardwood Floors

FLUSH MODEL

For maximum air flow, use this traditional egg-crate style with 3/8" wide webs. The open area of the Flush Model is the size of the opening, to which 1" wide ends and rails are added and fully doweled to each of the web members. Frames are cut from 1-1/4" wide stock, doweled at each corner. The frame is glued and blind-nailed to the subfloor and the flooring fitted to it. When finishing is complete, the vent is placed in the frame.

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 3/4" wide. Fluted dowels secure each web to the 1-1/4" wide side rails and end pieces. Specify the exact opening size when ordering.
