Nestaflex 175 flexible expandable skatewheel conveyor

I picked up four of these and don't need all of them.
I believe that the following ad text applies to this item:
Axle Centers Standard 5-1/4" axle centers. To accommodate small packages, restrictors are available for 3" or 4" centers.
Leg Sets and 2-Point Connection 1-1/8" OD, 12-gauge steel tubing with adjustable inner leg and single cross-brace, zinc plated. Two-point bolted leg connection to skate wheel axles and side links.
Height Adjustment Optional: 20" to 28" (Longer legs are available if needed.)
Side Links and Connections 11-gauge, zinc-plated steel. Top connections are provided by 5/16" steel axles with lock nuts. Cross-point connections are steel pivot pints with spring-loaded retainers. Bottom connections are a combination of pivot pins and 5/16" steel tie rods.
Box Stop/Handle Heavy-duty 1-1/8" OD, 12-gauge steel tubing with 1/4" steel brackets, zinc plated. Box stop folds down when connecting the conveyor to equipment or other conveyors. The box stop is also a convenient push/pull handle.
Couplers To link conveyors together, each unit is equipped with one set of 7-gauge steel couplers opposite the box stop end. Conveyors may also be added to the box stop end.
