Outdoor Lockable Poster Case - Black A1


Poster case is perfect for the display of a single poster


Poster cases are mainly intended to display a poster matched to the size of the case . The poster is secured by plastic clips concealed behind the rim of the door.  As well as displaying posters printed on paper the display case will accept thicker card and other flexible substrates up to 1.5mm thick.


If you wish to use a Poster Case as a notice board (e.g. for multiple A4 sheets rather than a single poster) the individual notices will need to be secured to the back panel by sticky dots or Blu Tack.  There isn't sufficient space behind the door for pin heads and moreover the backing board in not designed to accept pins or thumb tacks.

Condensation on the inside of the door can occur under certain atmospheric conditions. It is the same situation as inside a car windscreen where condensation can occur without implying that rain has actually entered.


Typically on a cold night after a humid day the water vapour in the air can condense on any cold surface (such as the glazed door or car windscreen) and this is unavoidable. In most situations any misting clears of its own accord as the glass (or clear plastic) warms up again.


Some suitable applications for keylock poster cases.

The lockable poster case is a graphic holder sometimes referred to as an outdoor sign display case or keylock poster frame. With its hinged door, aluminium frame and wall mount fixings, the unit is practical and great value. We believe it's a cheap poster case for the quality!


One popular application is as a wall mounted menu holder for a restaurant or pub. It is very easy to change the contents so this poster case is ideal for displaying daily menus.


As an outdoor holder for posters it's weatherproof and attractive. It looks equally good if you want to display posters indoors whether in a school, public building, factory or hospital.


It can be used for poster display in many situations: as a theatre poster frame, cinema poster frame, quad movie poster case (30x40" size) for outdoors, in poster displays for the public, as an oudoor poster case for advertising forthcoming events.


As well as being a wall mount sign holder they are used as movie poster cases oudoor or indoor.
