- Different configurations of barrels are used to create all of the weights used in current standard array geometries (200, 400, 700, 1400, and 2100 lbs).
- External sand weight verification is easy — just use the right configuration barrel to obtain the correct weight.
- Sand leaking is eliminated because each sand container is one piece — no edge seals. Shipping, storing, and installation is easy because there are no cone inserts.
- Optional lifting and dumping ring available — barrel shoulder allows for easy lifting and emptying.
