These are preowned from a local estate sale so I only know what I am reading the the company website for this model item. Picture is of one of them but I have several. These will come exactly as pictured. The picture with the sticker is showing the model number, The serial number may be different as I only took picture of one. From the website it is saying this can hold up to 24" monitor or tablet. This is a hard mount to a table or desk. THERE ARE NO CLAMPS OR HARDWARE TO MOUNT THESE> YOU WOULD NEED BOLTS OR SCREWS TO ATTACH TO YOUR SURFACE OF CHOICE
