Cover sheets, chalk cards, laminating pouches | Useful poster frame inserts

Poster cover sheets and blackboard inserts


  • Poster Protectors and Cover Sheets are available in two grades: standard thickness covers for snap frames and lightweight poster protector sheets for slot-in frames.

  • Chalk Cards are used to convert poster frames into blackboards for writing on with chalk pens.  Versatile write-on inserts for poster frames to convert them to slate boards.

  • Laminating Pouches are for encapsulating paper prints to make them water-proof.  They are an ideal complement to laminated size poster frames.

  • Correx Sheets are supplied with some of our top-loading frames as a stiffener; these Correx sheets are for use as replacement backing sheets.

Snap frame replacement plastic covers

Replacement covers for snap frames are also known as poster cover sheets. These high quality plastic sheets are suitable for most types of snap frames as replacement covers. They are suitable for regular snap frame pavement signs which do not have a waterproof gasket (most A-boards and budget waterbase signs). 

Important Note:
Snap frame replacment covers are supplied pre-cut to specific sizes. Please check dimensions carefully before ordering. See paper size guide.
Waterproof snap frames and snap frames for higher quality water-base pavement signs with a rubber gasket within the frame require special over-size faces (Click here).
Lightweight poster protectors are available for plastic Slim Frames only.

  • 500 micron anti-glare cover sheets for snap frames.
  • Made from outdoor grade PET (similar to PVC but better quality).

Oversize covers for waterproof snap frames

When waterproof snap frames require replacement covers it is important to select the correct size. 

  • If you see a black rubber strip all round the inside of the snap frame you will need one of these oversize poster protectors.

These PET covers are larger than than corresponding regular snap frame covers and will fit our waterproof snap frames and waterbase pavement signs as specified below. An oversize snap frame cover is required to span the rubber gasket which surrounds the poster aperture in a waterproof snap frame in order to achieve a good seal.

When purchasing to fit other manufacturers' snap frames please check measurements carefully as we cannot advise on compatibility with other makes, nor is it economical to accept returns for wrongly ordered poster covers.  Please refer to the exact dimensions of the covers in mm stated below.
