The bottom line: this anchor is straightforward, heavy duty, and designed for concrete-only applications, with the biggest reason to buy being its complete packaged hardware and simple installation process that saves time on site.

Key Features

• Zinc plated finish: Helps prevent rust in dry environments so installed anchors keep their appearance and function where moisture is not present.
