SWAY BRACE – SEISMIC
Fig. 771 Sway Brace Swivel Attachment
Fig. 770 Q Brace Clamp
Size Range: Service Pipe: 1" through 6" Sch. 10 and Sch. 40 IPS UL and FM Approved
Service Pipe: 1" through 6" Flow Pipe FM Approved
Brace Pipe: 1" or 11/4" Sch. 40 IPS
Material: Carbon steel
Finish: Brace Rod q Plain or q Galvanized, Channel bracket EG
Service: Used to rigidly brace piping systems subjected to sway and seismic disturbances. Pipe
clamp component of Anvil's 700 series sway brace assembly. Primarily a lateral brace clamp and
applicable as a riser/four way brace.
Approvals: UL and ULC Listed (UL 203A:2009), and FM Approved (FM 1950:2010). Complies
with seismic bracing requirements of NFPA-13. Office of Statewide Health Planning and
Development (OSHPD) State of California approved.
Features:
• Used to brace schedules 10 IPS, 40 IPS (UL and FM), and Sch. 7 IPS flow pipe (FM).
• Field adjustable design requires no threading of bracing pipe
• Can be used as a component of a four-way brace support
• Functions as a lateral brace application
Installation Instructions:
1. Minimum brace pipe extension 2" beyond channel bracket or brace clamp rod end. Note: 6" sizes are supplied with retaining
plate that assembles between sprinkler system pipe and brace pipe. Not required for FM applications.
2. The brace clamp channel bracket can be installed inside or outside the service pipe at the end of the brace pipe.
3. The Q brace clamp must be a minimum of 6" away from a pipe joint in order to not weaken the pipe joint.
4. Riser/4-way brace - The Q brace clamps must be installed within 6" of each other.
5. Adjust brace angle as necessary.
6. Tighten hex nuts until spring indicating clip is completely flattened and the required torque of 14 Ft-Lbs is achieved. For sizes
2" - 3", 4" x 1", 5" x 1", and 6" continue tightening to a torque of 16 Ft-Lbs.
Ordering: Specify service pipe diameter, brace pipe diameter, figure number, name and finish.
OPA-2804-10
Notes:
1. For fire protection installations - sway braces are intended to be
installed in accordance with NFPA-13 and Anvil's installations
instructions and local codes.
2. The required type, number and size of fasteners used for the
structural attachment fitting shall be in accordance with NFPA-13.
3. To assure proper performance, installer is responsible for:
a. Structural integrity of attachment member to safely handle
load requirements.
b. Securely tightening the component on the brace pipe.
4. Anvil International® brand bracing components are designed to be
compatible ONLY with other Anvil International® brand bracing
components, resulting in a Listed seismic bracing assembly.

* See FM Approval guide for approved flow pipe.
** The allowable FM approved capacity of brace subassemblies have been determined
by resolving the load rating to the horizontal direction and dividing by a safety factor
of 1.5 to allow the values to be used directly for Allowable Stress Design.
For Load Resistance Factor Design (LRFD) capacities, the above values will need
to be multiplied by 1.5.
*** Brace Pipe Angles are determined from vertical.
