Why The Powernail 445LSW Is Worth The Investment

This isn't just a flooring nailer, it's the industry standard 16-gauge Powernailer used across the domestic hardwood flooring trade, giving flooring contractors thicker, stronger cleats than the 18-gauge FLEX model for superior holding power on standard oak, maple, ash, and pine installations.

The 445LSW specifically addresses the needs of flooring contractors installing standard domestic hardwood species who want the widely recognized industry-standard tool, backed by Powernail's best-in-business warranty coverage.

The Industry Standard For A Reason. As the recognized industry standard for installing 3/4" and 5/8" domestic hardwood flooring, this nailer's 16-gauge cleats deliver superior holding power compared to thinner 18-gauge fasteners, making it the go-to choice for oak, maple, ash, pine, cherry, and walnut installations across the trade.
