The Datalogic HLD-G041-BK is a black G041 holder designed for desk or wall mounting. It provides a designated place to keep compatible scanning equipment when it is not being held in hand.
Datalogic lists this part in its Gryphon 4500 Series accessories under mounts and stands. Its desk/wall format gives you two placement options for organizing a scanner setup. The listing identifies it as a holder, rather than the separate G041 automatic stand.
This is the black version of the G041 desk/wall holder; the white version has a different part number, HLD-G041-WH.
