+ Tension is maintained post-install, in essence “cinching” the structure to the foundation with constant, lasting pressure
+ Exhaustive and established lab and shop testing of fully assembled components
+ Self-testing post-install, as strength builds when concrete further cures
+ Distinct state product approval
+ Diversity: utility in single and multi-family construction
+ Simplicity: less material for more uses to resist both overturning and uplift forces
+ Service: guaranteed quotes and signed and sealed engineer drawings
+ No expensive take-up devices required
+ Installed after framing with simple,quick methods
+ Fewer, easier inspections
+ No nails. No tricky, long and unworkable stiff rods
+ Few tools needed.
+ Flexibility on plumb tolerance adds to ease of installation.
+ No solution for wood shrinkage and building settlement
+ Straps buckle, possibly causing stucco cracking and water intrusion.
+ Finish blemishes when mounted to sheathing.
+ Plethora of nails damage the studs
+ Exhausting. Part and pieces are endless. Various type of hardware is required for the various forces necessary to resist.
+ Laborious: the time and energy required to install is costly
+ Multi-step process before, during and after framing.
+ Specific nail lengths and shanks required – hard to keep up with and verify
+ Heavy machinery for outside of the building components may be required
+ Little flexibility on tolerance
+ No natural solution for wood shrinkage and building settlement (take up devices required)
+ No product approval – rod is not product; it is a fabricated commodity
+ Questionable country of origin and history of quality problems
+ Unfinished rod shows rusts and can inhibit effectiveness of epoxy bond
+ Expensive take-up devices required to account for wood shrinkage and building settlement.
+ Reliant on the value-add of services (design and installation) not inherent in the product itself.
+ Difficult to work with; can be greasy
+ Bent rod must be culled and not installed
+ Embedment depth cannot be verified
