Product Overview: The Modern Secure Standard

The Cobolt 1200x900mm Tamperproof Grey Board is the facility manager's preferred choice for modern buildings. Stepping up in size to hold 12 x A4 sheets, it offers 50% more capacity than the smaller model, allowing for a comprehensive display of statutory and voluntary information. The combination of Sleek Grey Felt and a secure polycarbonate cover creates a "display case" feel that respects the design of your building while keeping contents safe.

Secure & Shatterproof

  • Vandal Resistant Glazing: We utilise optical-grade PET plastic for the door panel. Unlike glass, which poses a risk if smashed, this material absorbs impact and will not shatter, making it the safe, compliant choice for escape routes and public lobbies.
  • Lockable Integrity: The door is secured by a reliable key lock (2 keys included). This ensures that only authorised personnel—such as the building manager or head of department—can update the display, maintaining a tidy and professional appearance.
  • Internal Security: The wall fixings are located inside the lockable case. This means that once the door is locked, the board cannot be unscrewed from the wall, preventing theft of the entire unit.

Professional Capacity

  • 12-Sheet Display: The 1200x900mm dimensions are optimised to hold 12 x A4 sheets (arranged 4 across and 3 down in portrait, or vice versa). This provides ample space for fire certificates, insurance documents, and community news on one board.
  • Neutral Aesthetic: Grey felt is increasingly popular in corporate and residential developments. It hides dust and pin marks better than blue, and offers a neutral backdrop that doesn't clash with branded posters or interior paint schemes.
  • Robust Frame: The satin silver aluminium frame is structurally reinforced to support the larger door span, ensuring it closes flush and secure every time.

The Cobolt Standard

  • Free UK Mainland Delivery: We cover the shipping costs on all our tamperproof boards, ensuring a simple, transparent price for your procurement budget.
  • British Assembly: Our lockable range is assembled to high standards, ensuring reliable hinge operation and a quality finish that stands up to daily use.
  • Stock Availability: We hold deep stock of this versatile size, allowing for rapid dispatch to help you standardise your displays across multiple sites.
  • Complete Kit: Every board arrives with a secure wall fixing kit and a set of keys, enabling immediate installation by your maintenance team.

Where is this 1200x900mm Lockable Grey Board specified?

Expert Advice for Tamperproof Boards

Q: Is this board waterproof?

A: No, it is for indoor use. While it offers excellent protection, it is not sealed against driving rain. It is ideal for indoor corridors, receptions, and lobbies. For outdoor use, select our "External" range.

Q: How many A4 sheets does it hold?

A: It holds 12 x A4 sheets. This 4ft x 3ft board allows you to display a grid of 4 sheets across and 3 sheets down, offering significant capacity.

Q: Is the door glass?

A: No, it is shatterproof PET. We use a high-quality clear plastic glazing that is much safer than glass, as it will not shatter into dangerous shards if hit.

Q: How many keys come with it?

A: Two keys are supplied. This allows you to have a master key and a spare, or issue keys to two different authorised users.

Q: Can I use magnets?

A: No, this is a felt pinboard. You should use standard push pins or Velcro tabs to attach your notices. We do sell magnetic versions separately if required.

Q: How does it mount to the wall?

A: Through the inside. The fixing points are located inside the case (accessible only when the door is open), meaning the fixings are hidden and the board cannot be stolen when locked.

Q: Can I mount it portrait?

A: Yes. The board can be rotated to be mounted in Portrait format (900mm wide x 1200mm high). The door will simply hinge from the side.

Q: Why choose the Grey version?

A: Grey is modern and neutral. It is the preferred choice for architects and facility managers as it blends with modern office furniture and doesn't clash with different poster colours.

Expert Advice for Tamperproof Boards

Q: Is this board waterproof?

A: No, it is for indoor use. While it offers excellent protection, it is not sealed against driving rain. It is ideal for indoor corridors, receptions, and lobbies. For outdoor use, select our "External" range.

Q: How many A4 sheets does it hold?

A: It holds 12 x A4 sheets. This 4ft x 3ft board allows you to display a grid of 4 sheets across and 3 sheets down, offering significant capacity.

Q: Is the door glass?

A: No, it is shatterproof PET. We use a high-quality clear plastic glazing that is much safer than glass, as it will not shatter into dangerous shards if hit.

Q: How many keys come with it?

A: Two keys are supplied. This allows you to have a master key and a spare, or issue keys to two different authorised users.

Q: Can I use magnets?

A: No, this is a felt pinboard. You should use standard push pins or Velcro tabs to attach your notices. We do sell magnetic versions separately if required.

Q: How does it mount to the wall?

A: Through the inside. The fixing points are located inside the case (accessible only when the door is open), meaning the fixings are hidden and the board cannot be stolen when locked.

Q: Can I mount it portrait?

A: Yes. The board can be rotated to be mounted in Portrait format (900mm wide x 1200mm high). The door will simply hinge from the side.

Q: Why choose the Grey version?

A: Grey is modern and neutral. It is the preferred choice for architects and facility managers as it blends with modern office furniture and doesn't clash with different poster colours.
