External poster signs are a powerful advertising tool. With 70% of purchase decisions made in-store, driving footfall inside is key. Nothing does that better than Sentinel, in a choice of 3 high impact poster sizes – 30” x 40”, A0 and 40” x 60”.

  • Smooth rounded corners for safety.
  • Optional ‘Tactical Headers’.
  • Zinc phosphate and polyester powder coated steel frame (50 x 25mm oval).
  • Stainless steel tamper proof fixings retain poster cover at the top and enable ease of poster change by one person.
  • Silver border and frame as standard. Also available branded/printed in custom colours (minimum order quantity 25).
  • Back panel available printed to ensure presence when posters are not in use.
  • Clear polycarbonate poster covers offer high impact resistance and UV stability.
  • Magnetic poster covers provide superior weather resistance and poster security.
  • Water-fillable polyethylene base, precisely calculated for optimum stability, made using recycled materials.
  • Black base as standard to hide dirt and marks – also available in custom colours (minimum order quantity 100).
  • Built in wheels and purpose designed trolley, make it easy to move into position.
  • Lower cost, lighter weight base option available for 30” x 40” and A0 sizes. Volume/contract enquiries only.

Tactical Header also available, ideal for short term promotion. Giving additional advertising space for minimal cost.
