Wedge Anchors are a non-bottom bearing, wedge-style expansion anchor for use in solid concrete or grout-filled concrete masonry. A one-piece clip ensures uniform holding capacity that increases as tension is applied. Installation is simple, utilizing standard hole sizes equal to the anchor bolt diameter. Wedge Anchors are among the most common and economical anchoring option for existing concrete. Available in carbon steel with a zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.
