  1. All capacities shown are in Lbs.
  2. Beam capacities are for uniformly distributed loads.
  3. Beams over 116" length should be tied across the middle to prevent beam spread.
  4. Beams over 90" length that support loose deck, should be tied across the middle to prevent beam spread.
  5. Please call Factory for any Beam spacing on a Frame greater than 96".
  6. Values shown reflect the capacity of the Beams based on the lesser of its strength in bending or L/180 deflection criteria.
  7. Greyed out capacities in the top right hand corner of the chart, exceed the safe capacity of the connectors.
