Mailbox with outgoing tube Unimet A-4T, A4 document size, matte black

The Unimet A-4T mailbox with outgoing tube is a wall-mounted letterbox designed to accommodate A4-sized documents without folding. It combines a mail reception compartment with a rear-mounted outgoing tube for temporary storage of outgoing items. Finished in matte black, the mailbox offers a flat top slot suitable for envelopes, brochures and other flat mail, and is intended for installation at residential entrances, apartment buildings or small business premises where straightforward A4-capable mail handling is required.

Advantages

The design enables separate reception and temporary outgoing storage, reducing the need to handle items immediately. Its A4-capacity slot accepts full-size documents and magazines, avoiding damage from folding. The matte black finish provides a neutral, low-gloss appearance that resists glare and integrates with a range of exterior styles. The wall-mounted format saves ground space and positions mail at an accessible height for delivery and retrieval.

Suitable for

• Residential front doors and entryways
• Small offices and professional premises receiving A4 mail
• Apartment building lobbies where A4 documents are common
• Locations needing a temporary outgoing mail compartment

Key specifications

How to use

Install the mailbox on a secure vertical surface at a convenient height following local mounting recommendations and using appropriate fixings for the wall material. Deliveries are made through the top slot into the reception compartment; recipients open the front access to retrieve incoming items. Place outgoing envelopes into the rear or forward tube provided for temporary storage until collected. Regularly check and empty both compartments to prevent accumulation of wet or damaged items.

Usage recommendations

For best results, mount the mailbox in a sheltered location away from direct rain and strong sun. Use rust-resistant fixings when installing on exterior walls and periodically inspect seals and hinges. Avoid forcing bulky or overly thick parcels through the slot; route such items via alternative delivery arrangements.
