Thermwell ST26HRA Aluminum Threshold 3x36 High Rug

Product Description

The THERMWELL ST26HRA is a 3-inch by 36-inch aluminum threshold designed for the standard high rug profile. It bridges the transition between doorways and flooring, providing a secure, low-profile edge that accommodates thick pile carpets. The extruded aluminum construction offers durability in high-traffic residential and light commercial doorway applications. This threshold is installed by flooring professionals, general contractors, and experienced DIYers during door installation or flooring replacement projects. The design accepts a replaceable insert, extending the service life of the unit without full threshold replacement.

This threshold is suited for interior doorway transitions where thick pile or high-pile carpeting meets a hard floor surface or room divider. It is commonly installed in residential entryways, hallways, and bedroom doorways where carpet height requires an elevated threshold profile. The package includes 6 units per pack, making it practical for multi-door installations or contractor stocking. When the insert wears, it can be replaced using the compatible RV36H insert rather than replacing the entire threshold assembly.

Installation Notes

Installation is typically performed by flooring contractors or general contractors using standard hand tools including a drill, screwdriver, and hacksaw for length trimming if needed. Power down any automatic door operators before installation. Secure the threshold to the subfloor per the manufacturer fastener pattern to prevent shifting under foot traffic. When replacing only the insert, remove the existing insert from the channel before pressing or snapping in the RV36H replacement.
