SPF100 – Seismic Pivot Fitting

The SPF 100 is a 45° fixed 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 100 platform is not included in this assembly and is sold separately.
