Features a full-size 9/16" band and housing width that allows 12-1/2 percent more sealing area over conventional 1/2" bands. One piece housing and interlocked construction. Mechanical design locks the one piece housing directly to the band using the full strength of the material to provide maximum anti-shear protection. No spot welds to rupture under stress or corrosion. One piece housing will not come apart under high loading. 5/16" hex-head screw. Especially suited to industrial applications.
