While intermittent welding might pass structural calculations, continuous fillet welds provide superior fatigue resistance and prevent moisture entrapment, minimizing crevice corrosion behind the chair assembly.

While standard anchor bolt chairs are designed to distribute local loads and minimize secondary bending in the shell, they can sometimes overstress light base rings or shells when spaced too closely. The AISI standard provides specific guidelines for this "better" alternative: The Continuous Top Ring Feature aisi e 1 volume ii part vii anchor bolt chairs better

No more guessing if the chair will pull through the concrete under uplift loads. You get calculable, reliable performance. You get calculable, reliable performance

An anchor bolt chair is a specialized structural component—usually made of steel—designed to hold anchor bolts securely in their exact, intended positions before and during the concrete pour. You get calculable

Using the offers several advantages over simple gussets or direct bolting:
