Through trial and error, i found that this product was the best solution for carrying and adjusting heavy sheets of plywood and sheetrock on construction sites .Its adjustable design allowed me to easily maneuver and transport materials from one location to another, without straining my back or causing any damage to the materials. The lightweight design and compact size make it a great addition to any industrial and scientific workplace. the only downside is that it may not be suitable for extremely large sheets of materials..
