Thermwell WAT36H Oak Threshold 36 Inches Exterior

Product Description

The THERMWELL WAT36H is a clear grade oak door threshold designed for exterior low rug applications. Measuring 3.5 inches wide, 0.625 inches tall, and 36 inches in length, this solid wood threshold bridges the gap between a door bottom and the floor surface to reduce drafts and energy loss. Clear grade oak provides a tight, consistent grain structure suited for high-traffic entry points. No vinyl insert is included, keeping the profile low and unobtrusive for rug-level transitions. Licensed contractors and skilled tradespeople install this threshold as part of weatherization and door hardware work.

This threshold is suited for residential exterior doorways where a low-profile transition is needed between the door bottom and a rug or floor surface. The 36-inch length fits most standard single exterior door openings. Its clear grade oak construction is appropriate for painted or stained finish applications. The absence of a vinyl insert keeps the height minimal, making it compatible with low-pile exterior mats and rugs at entry points.

Installation Notes

Installation is typically performed by a carpenter, general contractor, or experienced handyman as part of door weatherization work. Power down any electrically operated door hardware before beginning work. The threshold is typically secured with countersunk screws through the face into the subfloor or sill; pre-drilling is recommended to prevent splitting in oak. Finish the surface with an appropriate exterior-grade stain or paint after fitting to protect the wood from moisture.
