These carts are used, and appear to be in good, fully functional condition.
(Note to scammers: don't waste your time.)
Their rubber clamps are in good condition on both pieces. The in-channel padding looks functional (with one notable rip near the edge of the HD1- the larger one). Tires have a few marks but look functional. These dollies seem to have been well cared for by their previous owner. Depending on user preference, they may not require any additional work to be in useable condition, and can likely be used immediately.
These specialty dollies are made for professional "stone and glass transportation, featuring integrated clamps, high ground clearance, and reliable non-marking tires" (omnicubed.com).
Both are made of light weight aluminum, but each can carry 750lbs. Perfect for the tradesman looking to expand.
