Features a full-size 9/16 in band and housing width that allows 12-1/2% more sealing area over conventional 1/2 in 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 in hex-head screw. Especially suited to industrial applications.
