SPF ® 100 - Seismic Pivot Fittings ꞏ Notes: 1. Design load is limited to slip capacity of a channel nut at hole "R". 2. Allowable loads have been determined by the manufacturers testing, analysis and technical specifications. 3. For retrofit application, engineer of record must verify. 4. Square washer provided with fitting. 5. When a hanger rod is thru-bolted (in lieu of channel nut installation), higher transverse loads may be transmitted due to the higher allowed rod shear loads compared to channel nut slip Seismic Components
