The innovative design of the LSSR Slopeable & Skewable Rafter Hanger allows it to adjust for skew up to 45° and features an innovative hinged swivel seat to adjust for up to a 45° slope on site, eliminating the need for pre‑skewed/sloped or custom‑order hangers. One of its key features is that it can be installed after all of the rafters have been tacked into place. Now one hanger can handle a wide range of framing applications.

Please check the Corrosion Information to see if it is suitable for your application.

(1). Design Capacity is the lesser of (a) the Characteristic Capacity multiplied by the NZ Strength Reduction Factor (φ), and applicable the k modification factors following NZS 3603 and (b) the Serviceability Capacity which is the load at 3.2mm joint slip. Design Capacity is the minimum of test data and structural joint calculation. (2). The Strength Reduction Factor (φ) is 0.80 for nails in lateral loading. (3). Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor where applicable. Capacities may not be increased. (4). Timber species for joint design is seasoned Radiata Pine, which is New Zealand Joint Group J5 per NZS 3603 Table 4.1. (5). On the acute side of the skewed LSSR hangers, fill obround holes only.
