4 Gripple Seismic Restraint systems are ideal for use on nonstructural components and equipment requiring Seismic design, such as in essential facilities that are required for emergency operations in the aftermath of an in this Manual are bracing guidelines for a variety of nonstructural components, equipment, and systems. Actual restraint requirements for some sites may vary from these guidelines, and these site-specifi c restraint installations are not limited to the guidelines detailed here. However, ensure that any deviations from the guidelines within this Manual are pre-approved by the Seismic engineer of record for the particular site. It is the responsibility of the reader and structural engineer for the project/site to ensure that the existing structure is capable of withstanding the full loads that may be induced by the braced equipment or Seismic attachments. The services of a Seismic bracing engineer or a professional/structural engineer is required to determine the Seismic demand forces, required bracing, spacing, and anchorage of the bracing in accordance with the applicable building code design provisions and conditions for the note that this Manual does not replace code-required industry standard practices.

5 Gripple Seismic Restraint systems, designed as per the guidelines outlined in this Manual , do not guarantee adequacy of the Installation , and it is the responsibility of the reader and structural engineer for the site/project to ensure the adequacy of the design and placement of the Seismic bracing kits and their Installation to be in compliance with the applicable :Neither Michael J. Griffi n nor Gripple are the Structural or Professional Engineers of Record. The stability and adequacy of the structural elements, nonstructural components or Seismic sway braces, hangers, brackets, bolting, anchorage and any other required attachments are the responsibility of the Structural or Professional Engineer of Record, or the Seismic bracing design engineer for the Facility or Project. Any additional or supplementary members required to ensure the adequacy or stability of the structures the Seismic sway bracing attaches to are not within the scope of this Manual /document. Gripple warrants that the Gripple Seismic Restraint systems will achieve the applicable design strengths published if installed in accordance with the guidelines contained in this Manual .
