A1 Black Adhesive Window Poster Holder - Single-Sided, Full Back Adhesive

A1 black adhesive window poster holder for 594 x 841 mm posters - the largest size in this range. The flexible frame sticks to the inside of the glass and the clear front sheet is held on by magnets, so a poster change takes seconds and the frame stays where it is.

At A1 the whole back is adhesive rather than a strip around the edge. A poster this big needs the extra bond to stay up, which is why this size is single-sided: the back is covered by the adhesive, so the poster is read from one side.

Questions & Answers

Q: Why is A1 single-sided when A3 is double-sided?
A: The smaller sizes hold with a strip of adhesive around the edge, which leaves the back clear so the poster can be read from both sides. An A1 sheet is heavy enough that a strip is not reliable, so the whole back is bonded to the glass.

Q: What surfaces will it stick to?
A: Glass, mirror, tile, laminate and painted plasterboard - anything smooth, clean and dry. It will not grip render, brick or a textured wall.

Q: How do I change the poster?
A: Lift the clear front sheet, which is held by magnets in the frame, slide the old poster out and the new one in, then let the sheet drop back. The frame stays on the glass.

Q: Can I peel it off and move it?
A: Plan the position first. The adhesive is meant to go on once - peeling it off to reposition weakens it.

Q: Can I use it outdoors?
A: It is made for indoor use, stuck to the inside of the glass. Outside, or in a window that gets hours of hard sun, the sheet yellows and the adhesive gives up sooner.
