TelPro Troll Panel Handler, Yellow, 1-(Pack)

Does two work better than one?

Will this support garage door panels? Im trying to find something to help assist my husband who has to carry the panels on his own.

Why is a 1-pack $40 and the 2-pack is almost double of what two 1-packs would be?

Can this help move a folded banquet table whose width when folded is almost 3 inches wide...thgts??? that is much wider than a piece of drywall.. thnx
