Benefit from a case that is weatherproof and can be used indoors and outdoors. No more soggy notices or displays that are constantly walked past. Give people a reason to stop and read the information displayed inside your amazing new case by putting it somewhere obvious; safe in the knowledge that it’s built for any eventuality with its tight, waterproof seal.

These products are, obviously, lockable. Larger cases or frames will come with two locks, while standard and smaller frames have a single lock on the right of the frame. Frames are supplied with two keys per lock; so, you can keep one on your person at all times and have a back-up in a safe place in case you need it.

Frames come in a range of sizes, from A0 paper size to A5 paper size. Also offered specifically from us at Red17 are frames that are 30 inches by 20 inches, 40 inches by 30 inches, and 60 inches by 40 inches. We can also offer you 17 different stock colours for our standard outdoor lockable poster cases, as well as a simple and elegant black colour for our slimlok design.

Lockable cases at home

Display awards charts for your children without giving them the ability to change things around or play with it. Display precious memories away from young children who, let’s be honest, get into everything. Or even just keep a few things safe by utilising the space of a box that can be locked but is cheaper than most functioning safes.

A really great idea is to use a lockable case as a holiday countdown; letting the case hold pictures, things to remember, and even the money you’re putting aside for your new adventure.

Lockable cases at school

Use the case to communicate with parents! For any upcoming school trips or events, having a visible poster displayed is a powerful thing. Children can often forget to tell their parents important things when they’re young, and a poster case right at the entrance to the classroom or the parent-child drop-off point is a great use of the space.
