What is the difference between a transaction counter height and a work surface height on a reception desk?

The transaction counter (42") is the raised front panel visitors approach. The work surface (29"–30") is behind it where the receptionist sits. ADA units add a third surface at ≤36". Confusing these when ordering is one of the most common mistakes we see at OfficeFurniture2go.com. Our product listings always call out all three heights — and our team at 1-800-460-0858 will confirm them before your order ships.
