SIZE: Anchors tested were 3-1/2" (88.9mm) long from the face of the concrete x 1" (25.4mm) wide Mill galvanized Sheet Steel conforming to ASTM A 527 G90 for 16 gage and ASTM A 526 G90 for 12 gage.
APPLICATION: Anchors are installed in Dovetail Anchor Slots which are cast into concrete columns or walls. Usual installation is 16" (406.4mm) o.c. vertically.
TEST CONDITIONS: Anchors were embedded 2-3/4" (69.85mm) deep in the horizontal joint between two common bricks with Type N Mortar mixed 3-1 ratio and allowed to stand over 28 days (Approximately 3500 psi). Mortar joints were approximately 5/8" (15.87mm) with the anchors centered in the joints permitting mortar on both sides of the anchor corrugation. The samples were tested to failure at a crosshead speed of 0.5"/minute (12.7mm/minute).
