Frequently Asked Questions
Will a letter sorter hold A4 or standard letter-size paper?
Most metal mesh and multi-tier organizers are designed for A4 and letter-size paper — check the product dimensions and tray spacing. The Marbrasse unit specifically lists compatibility with A4 folders and standard magazines.
Can an under-desk tray damage my desk during installation?
No-drill C-clamps include protective pads to minimize scratching and pressure marks; still, confirm your desk thickness and underside condition. If your desk has rounded edges or crossbars, a clamp-style tray may not fit securely.
How durable are metal mesh organizers compared with plastic?
Metal mesh with a steel frame typically offers better long-term durability and resists sagging under heavy paper loads. Plastic models can be lighter and cheaper but may flex or crack over time if overloaded.
