Desk Document Holder

This freestanding copyholder sits securely on a desk thanks to its nonskid base. A sliding clip adjusts to hold pages in either portrait or landscape orientation. The grooved ledge supports up to 150 sheets and oversized documents. An adjustable line guide assists with data entry and prevents papers from shifting.

Users Needing Adjustable Viewing

The holder suits anyone who transcribes from paper while typing and wants a stable, angle-adjustable stand. It also folds completely flat for compact storage between tasks. Buyers who need a wall-mounted or monitor-attached solution should look elsewhere. Anyone requiring capacity beyond 150 sheets will find this model limiting.

150-Sheet Capacity

The maximum load of 150 sheets is the key figure that decides if this accessory fits the workload. Lighter jobs stay firmly in place on the grooved ledge and clip. Heavier reference binders or large stacks exceed the rated limit and risk instability. Match the sheet count to the holder rating before purchase.

Questions about this item

Will the 150-sheet clip hold documents steady if my desk surface is slightly uneven?

The copyholder has a nonskid bottom that keeps it stable on worksurfaces, and the grooved ledge with sliding clip secures up to 150 sheets in portrait or landscape orientation.

How can I confirm the line guide is set correctly for data entry?

The adjustable line guide slides to the desired row; when positioned, it holds the document flat so the current line stays visible and pages do not shift during typing.

Does the box include any extra clips or a separate line guide, or just the single unit?

The product is sold as one each: the fold-flat copyholder with integrated sliding clip, grooved ledge and adjustable line guide — no additional accessories are included.
