Table Notes 1-11
- Two Spanning Angles required per Suspension Clamp System, purchase though your local vendor.
- Angles are back-to-back, but spaced apart by Suspension Clamps.
- Allowable net load, per pair, may be located anywhere along the span. Weight of angles has been accounted for.
- Angle dimensions are listed “Vertical Leg” x “Horizontal Leg” x “Thickness”.
- No values below 500 lbs. are listed. Allowable loads have been limited to 2,000 lbs. maximum.
- Allowable loads are based on 36 ksi minimum yield steel and the AISC specifications.
- A single load equal to the tabulated capacity or multiple loads with a sum equal to the tabulated capacity is allowable.
- Live Load Capacities based on Safety Factor of 2.0.
- Loads in bold (528) are governed by deflection limit of Span/240; (e.g., 0.500″ for 10′ span).
- Tabulated values are based upon the additional bracing provided by Suspension Clamp System.
- Tabulated loads based on vertical loading only.
