SPF200 – Adjustable Seismic Pivot Fitting

The SPF 200 is an adjustable angle retrofit fitting for use primarily with seismic braces. This fitting can be used to attach a strut brace to a trapeze or other strut connection.

As a retrofit fitting, this product can be used to attach a seismic brace to an existing support without the need to disassemble that support.

The LS 200 platform is not included in this assembly and is sold separately.

This fitting is pre-approved for the below seismic loads on page 5c.2 of Unistrut’s OPM-0295-13.


Part No. Rod Size Hole Diameter Finish
SPF 200-037 3/8″ (10) 7/16″ (11) EG
SPF 200-050 1/2″ (13) 9/16″ (14) EG
SPF 200-062 5/8″ (16) 11/16″ (18) EG
SPF 200-075 3/4″ (19) 13/16″ (21) EG


Design load is limited to slip capacity of a channel nut at hole “R”.
Allowable loads have been determined by the manufacturers testing, analysis and technical specifications at 45° from horizontal.
For retrofit applications, engineer of record must verify.
Square washer provided with fitting.
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 values. This higher load may be used with verification through engineering calculations.

Materials & Finishes:

  • Electrogalvanized (EG):  Conforms to ASTM B633, Type III SC1 or SC3



Seismic Design Loads are based on FM1950-10 dynamic testing with 12 ga. channel and a safety factor of 1.5.
1/2″ Unistrut Channel Nut and Cap Screw torqued to 50 ft-lbs required for installation.
Reference page 5c.2 of Unistrut OPM-0295-13.
These capacities do not apply to the SPF200-037.
