Domestic or Office Situations
Poster Clamps can be used for displaying large or heavy posters on a wall in a domestic environment or in an office, school etc. They are completely reusable. For example they can be used for hanging large posters or maps - always choose the model to suit the width of the paper as the drop dimension is immaterial. The heavy bottom clamp rail will help straighten curled or rolled up charts and banners.
You will just have to consider how you're going to attach the Poster Clamp to the wall - you can use various types of picture hooks, pins or hang on a screw head. The slide-along hanging eyes on the top rail of the Poster Clamp can then be hooked onto the chosen fixing - and removed again or the poster exchanged as required.
Commercial or Retail Applications
In commercial situations Poster Clamps are generally hung from the ceiling using screw-in, clip-on or heavy-duty self-adhesive ceiling attachment fittings combined with fixed length or extending double-ended hooks or wires.
Poster Clamps offer a tenacious grip on many hard-to-grip banner materials. They are also suitable for tough hanging applications, for example long banners (several metres of drop).
A particular advantage of the Poster Clamp is that it is easy to position the banner precisely before clamping. With snap action versions the banner may tend to 'jump' out of position as the bars are closed. This is avoided with Poster Clamps.
Poster Clamps are not really suitable for substrates thicker than about 0.5mm (500 micron). It will be hard to close and re-open the poster clamping bar. Typical banner substrates are 200 micron to 350 micron thick and Poster Clamps are suitable for hanging drop banners of this type.
Poster Clamp Joiners
Joiners are supplied as a pair allowing two sets of Poster Clamps to be joined together.
First remove the relevant black end caps. Then insert the joiner midway into both profiles. A small thumbwheel is tightened from the back of the profile to achieve a firm butt joint. Each individual section should be properly suspended so as to avoid undue strain on the joiner, although they are strong.
Using Joiners offers further advantages. There is less chance of damage in transit to very long profiles and over-length carriage charges can be avoided. Clamping the graphic is easier to achieve in sections. When the clamp profiles are closed the join is hardly visible from the front.
