I-Beam or Tube?
There is a reason why Andrae D'Acquisto came out with a 100% cast aluminum platform and seat so many years ago, because tubes are extremely noisy. Our new, patented cast aluminum I-beam center offers the most advanced camouflage, is strong, light and dead silent. This new design only used by XOP sets us apart from our competitors that incorporate hollow tube construction in their designs. Its classic I-beam structure is the same design used on bridges. Ever been on a bridge make of hollow tubes? No, there is a good reason why.
The choice is clear, XOP's I-Beam
