Field-Adjustable Sloped and Skewed Hangers — Introducing New LSSR Sizes By The Simpson Strong-Tie Team
W
ith the recent introduction of our new LSSR rafter hangers for 2x lumber, we thought we’d provide some background on how these new hangers were developed and why.
Field-adjustable sloped and skewed hangers allow designers to specify widely available, economical connection solutions. They were first developed to improve on traditional sloped and skewed hangers that had to be special-ordered or custom manufactured. While specialorder hangers are still sometimes necessary, having off-the-shelf, field-adjustable joist hangers gives designers an attractive alternative for many common conditions. The discontinued LSSU joist hanger series, which the LSSR replaces, needed to be installed before the joists were in place. We heard from installers that it would be helpful for job sequencing if the hangers could be installed after the joists or rafters were tacked into place. This feedback led us to design our LSSR and LSSJ hangers, both of which are easy to adjust in the field and can be installed after joists or rafters are in place. Building designs often require connections for supported members that are at a skewed and sloped angle rather than perpendicular to the header. Several of our other hanger series are adjustable for skew only or slope only, but not for both. For example, our THASR/L series is designed to accommodate connections skewed from 22 1/2° to 75°. Conversely, the LRUZ ridge hanger is designed to support rafters at ridge beams with roof slopes of 0:12 to 14:12. Finally, our SUR/SUL/ HSUR/HSUL series is not adjustable, but the models are manufactured with a fixed right or left skew of 45° in sizes to accommodate several joist sizes. The LSU/LSSU and LSSJ series field-adjustable hangers were developed to offer our customers off-the-shelf accessibility and convenience so they
