Strap may be bent one full cycle (bent horizontal 90° then bent vertical) to aid wall placement, but may cause spalling behind the strap. If the spall is 1 in. or less, measured from the embedment line to the bottom of the spall, full loads apply. STHD10 and STHD14 achieve full load for spalls less than 4 in,. Any portion of the strap left exposed should be protected against corrosion. See General Notes for Holdowns and Tension Ties. Fasteners: 0.148 x 3-1/4 in.
