Post Lockers

Q: What is a post slot locker?

A post slot locker is a secure locker unit that includes a slot in each compartment door so that letters, small bundles, or documents can be dropped in without opening the main locker door. This allows mail or messages to be delivered securely while maintaining the contents behind locked doors.

Q: How do you use post lockers?

Post lockers can be used by pushing the letter into the slot above the recipient’s locker door. The addressee can then open the post locker with a key, giving them quick access to their mail.

Q: Why should you use post lockers?

Post lockers are great for sorting internal mail, usually in office post rooms. This creates a quick and easy sorting process, and keeps letters organised in a safe space, ready to be accessed by the desired recipient.

Q: How much can I fit in a post locker?

Our post lockers have a letter slot size of 241 x 37mm (WxH). This gives ample room for letters to be pushed into the post locker slot. Inside, there is enough space for stacks of letters to be collected, should there be a delay in the locker being opened.

Q: Are post lockers secure?

Post lockers guarantee privacy for letter recipients, with their mail safely stowed away. Our post lockers are strong and durable, secured with a micro sprung 10 disk key lock. Lock upgrades are also available upon request.

Q: Can I use these lockers for parcels or bulky post?

Post slot lockers are best suited for letters, envelopes, and flatter parcels. Because the slot is limited in size, larger or bulky parcels may not fit through the slot and therefore are not suitable for drop‑through delivery.

Q: What door clearance size should I expect?

The opening size for post slot entry is always smaller than the full internal compartment, since the slot itself is designed just for dropping in post or thin items. Check the product specification for details on each model.

Q: What locking types are available for post lockers?

Typically they use key locks; compartments are individually locked. Some models may allow upgrade to padlock use or different locking mechanisms.

Q: How long will my post locker take to be delivered?

Usually post lockers take 5-6 weeks to be delivered, due to being “Made to Order” - delivery time is specified on each locker product page. Free delivery is offered to mainland UK locations.
