Multi-Fastener Adapter

Figure: 025

Function

Designed for bracing pipe against sway and seismic disturbances.  Sway brace adapter used to develop a greater structural connection by providing multiple fastener attachment points.  Adapter allows for 2 or 3 NFPA 13 approved fasteners to be used when one fastener is too weak to anchor a sway brace assembly to a structure.  Sway brace assemblies are intended to be installed in accordance with NFPA 13 and the manufacturer’s installation instructions.

Material: Carbon steel, 2” X 2” X 1/4” angle

Finish: Electro-galvanized

Size: 1/2” or 3/4” mounting holes. Braces up to 8” Pipe MAX

Install: Attach to the structural surface as noted in NFPA13 fastener tables. Please note that the two outermost bolt holes must be used and the middle bolt hole should be used only in conjunction with both outermost bolt holes to ensure concentric loading. Attach a PHD Manufacturing structural attachment fitting to PHD Fig. 025 and follow the instructions provided with said fitting.  The PHD structural attachment fitting can pivot around the mounting connection for adjustment to the desired brace angle.  Please note that the maximum load will be limited by the PHD Manufacturing structural attachment utilized with this adapter.

Approvals: Underwriters Laboratories listed for US and Canada. Listed for use with NFPA fastener tables and PHD sway brace components only.

Ordering: Specify figure number and fastener size.

NOTE: All connecting fasteners are sold separately.
