Pft 1 Preliminary testing to the new acceptance criteria for testing and evaluating holdowns(AC 155)indicates r. that the ultimate capacity divided by a factor of safety exceeds the previously calculated values; however, ,,ea - the allowable loads are limited by deflection under the new critieria. Since significantly lower deflections �i 15 are obtained with comparable SDS-style holdowns we recommend the use of the HDU series of holdowns sa (see page 37). For those conditions which necessitate a bolted holdown our existing HD product line R provides the best alternative for high loads at low deflection. rto HO holdowns a HD holdowns provide a bolted holdown solution. 1 /�. ' NEW!The 11019 is a high-capacity bolted holdown designed 4^I�I Minimum for applications that require loads beyond the capacity of the HDU �/ memo r series holdowns.The HD19 can be installed back-to-back when thickness maximum capacity is needed or when eccentricity is an issue.
