Aero-Seal Clamp

4-Piece Construction Band, saddle housing and screw
Full 9/16" Wide Bands 300 Series, stainless steel, with a finished edge to protect hose
"Arcial" Band Slots Arched on one side for strength, flat on bearing side for strength and smooth action.
Buttress-Thread, Heat Treated Screws Flat, non-tapered threads bear at right angles to band slots on loaded side; won't jump out. Sloping buttress shape reinforces unloaded side.
Clinched Saddle & Housing No spot welds to corrode or break. saddle interlocks into embossed band to form a true concentric circle. There are no lumps, no humps, no excessive pressure points, providing higher sealing pressure with lower torque on screw. Heavy gauge housing is clinched on four corners to interlocked saddle, permitting higher torque capabilities than any three piece clamp. Also available with safety collared or thumb screw.

Make-A-Clamp Kits

This is a maintenance "clamp system" in a box. By simply cutting off a piece of banding from a continuous roll, you can make any size 301 stainless steel worm driven clamp from 2" diameter and up. It's a must for anyone likely to encounter requirements for varying sized large clamps. 1/2" band width, .023" thickness. Reusable.
