2)  Trapeze Beam


Maximum Allowable Uniform Vertical Load (lbs)Trapeze Beam OPM Capacities

Notes:

1.  Values in this table apply only to Unistrut brand products. Unistrut channels are stamped with the name "UNISTRUT".

2.  Values in this table are valid with all solid, T, WT and HS pierced channels of the above channel profiles.

3.  * Load is limited by spot weld shear. Weld shear and tension are accounted for in the above listed capacities.

4.  Refer to OPM Page 4b.0 for the detailed calculation procedure.

3)  Brace Member


Maximum Horizontal FP Force (lbs) [ASD] at 45° from HorizontalBrace Member OPM Capacities

Notes:

1.  Values in this table apply only to Unistrut brand products. Unistrut channels are stamped with the name "UNISTRUT".

2.  Values in this table are valid with all solid, T, WT and HS pierced channels of the above channel profiles.

3.  Only the 45° capacities are shown above, but these brace members are valid for angles from 0° to 60° from horizontal. Refer to product or OPM pages for capacities at other angles.

4)  Brace Fitting


FP Load Capacity (lbs)

Brace Fitting OPM Capacities

Notes:

  1. Use with P3860 base.
  2. Use with LS 100 base.
  3. Use with LS 200 base.
  4. All angles above are from horizontal. All loads are based on use with a 1/2" or larger fastener and connected per one of the connection details outlined below.
