These items are designed to stand alongside a computer screen and hold an A4-sized document to assist with transcription. Both stands have various adjustable knobs so that they can be positioned and angled to suit the user. They also have "arms" that can extend from the side to support wider documents. Maximum height is approximately 60cm.
One stand has a fairly heavy base, a sprung clip at the top to grip a document, and a horizontal bar to track position down the page.
The other stand is designed to be screwed down, or be tucked under the adjacent computer or screen.
I'm happy for both stands to be taken together, or to split and donate them separately.
