Product FAQs

Product Overview: The Community Chronicle

The Cobolt 2400x1200mm Tamperproof Green Board is the definitive solution for managing large-scale community or educational information. Stepping up to the 8ft x 4ft Twin-Door Format, this unit provides the capacity to display entire terms' worth of schedules, town planning maps, and multiple A4 notices side-by-side. The Traditional Green interior fosters a sense of established trust and is the preferred choice for institutions where a professional, non-distracting appearance is required.

Twin-Door Practicality

  • Structural Safety: Spanning 2.4 metres, a single door would be unwieldy and dangerous in a crowded school corridor. We utilise a Double Door System with a central support bar. This keeps the doors lightweight and safe to open during lesson changes or busy events.
  • Dual Locking: Each door operates independently with its own key lock. This allows you to organise the board effectively—perhaps keeping "Fixed Statutory Notices" locked on the left, while updating "Weekly News" on the right.
  • Shatterproof Safety: We use optical-grade PET plastic for the glazing. It is tough, flexible, and will not shatter into dangerous shards, making it the only responsible choice for schools and public buildings.

Maximum Capacity

  • 24-Sheet Display: The 2400x1200mm interior is vast, capable of holding approximately 24 x A4 sheets (4 rows of 6). This capacity allows for the display of large "Whole School" policies or extensive parish financial reports without overlapping documents.
  • Visual Comfort: The green felt background reduces visual glare compared to whiteboards. It provides excellent contrast for white paper notices, making detailed text easier to read for visitors and staff.
  • Robust Frame: The anodised aluminium frame is corrosion-resistant and features reinforced corners to handle the weight of the double-door mechanism, ensuring long-term durability.

The Cobolt Standard

  • Free UK Mainland Delivery: Shipping 8ft twin-door boards requires specialist heavy-goods handling. We absorb these logistics costs to provide a simple, all-inclusive price for your school or council budget.
  • British Assembly: Our tamperproof range is assembled in the UK. We check the alignment of every double-door unit to ensure a flush finish before it leaves our warehouse.
  • Stock Availability: We hold stock of this grand format board, ready for immediate dispatch to help you prepare for the new term or fiscal year.
  • Complete Kit: Every board arrives with a secure wall fixing kit and keys, giving your caretaker everything they need for a secure installation.

Where is this 2400x1200mm Lockable Green Board specified?

The 2400mm x 1200mm Tamperproof Green Board is the standard for large-scale, traditional display. It is heavily utilised in:

  • School Assembly Halls: The central hub for "House Points," "Star of the Week," and safeguarding posters.
  • Parish Councils: Displaying large town planning maps and full meeting minutes in the village hall.
  • Church Entrances: A respectful, secure space for community outreach info, service times, and rotas.
  • Sports Pavilions: Keeping league tables, fixtures, and club rules safe and visible to all members.

Key Features

  • Twin Lockable Doors – Independent access to each side.
  • Shatterproof Glazing – Tough PET windows safe for schools.

Cobolt Service & Ethos: Direct from the Experts

  • 50 Years of Heritage: We have supplied the UK education and public sectors for half a century, understanding the specific needs of schools and councils.
  • Safety First: We prioritise safety. Our shatterproof doors and secure locks help you meet safeguarding obligations while keeping the display itself safe for students.
  • In-House UK Support: Need advice on wall suitability for this large unit? Our UK-based team is available to assist.
  • Project Expertise: Whether equipping a single hall or a nationwide academy trust, we have the stock and logistics to deliver.

Designed for Public Environments.

  • Impact Resistance: The PET glazing is designed to withstand the knocks and bumps of a busy school environment. Unlike glass cabinets which are a hazard, this unit will flex and absorb impact.
  • Double Door Reliability: By splitting the glazing into two doors, we reduce the stress on the hinges compared to a single large door. This ensures the unit remains easy to open and close for years.
  • Tamper Proofing: The locks are reliable cam mechanisms. When locked, the doors sit flush within the frame, making it extremely difficult to pry them open without the keys.
  • Secure Installation: The board is mounted through the backboard inside the case. This means the fixings are hidden and the unit cannot be removed from the wall while the doors are locked.
  • We offer a 1-year manufacturer's guarantee covering the locks, hinges, and frame integrity.

Expert Advice for Grand Format Boards

Q: Is this board waterproof?

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

Q: Why are there two doors?

A: For structural safety. A single door spanning 2.4 metres would be unsafe in a school corridor. The twin-door design ensures the unit remains rigid, safe, and easy to operate.

Q: How many A4 sheets does it hold?

A: Approx 24 x A4 sheets. You can typically fit 4 rows of 6 sheets (across both doors), making it perfect for whole-school or council-wide notices.

Q: Why choose the Green version?

A: Green is the traditional choice. It creates a calming, authoritative backdrop that is standard in British schools and councils, reducing glare and looking smart.

Q: Is the door glass?

A: No, it is shatterproof PET. We use a tough clear plastic that will not shatter into dangerous shards if hit by a bag or ball, making it the safest choice for schools.

Q: How many keys are provided?

A: Keys are provided for both locks. You will receive a set for each door, allowing for secure management of the contents.

Q: How is it installed?

A: Through internal fixing points. You open the doors to access the screw holes. We recommend two people for installation due to the weight and size.

Q: Can I use magnets on this board?

A: No. This is a felt pinboard designed for push pins or Velcro. If you require a magnetic surface, please view our magnetic whiteboard lockable range.

Expert Advice for Grand Format Boards

Q: Is this board waterproof?

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

Q: Why are there two doors?

A: For structural safety. A single door spanning 2.4 metres would be unsafe in a school corridor. The twin-door design ensures the unit remains rigid, safe, and easy to operate.

Q: How many A4 sheets does it hold?

A: Approx 24 x A4 sheets. You can typically fit 4 rows of 6 sheets (across both doors), making it perfect for whole-school or council-wide notices.

Q: Why choose the Green version?

A: Green is the traditional choice. It creates a calming, authoritative backdrop that is standard in British schools and councils, reducing glare and looking smart.

Q: Is the door glass?

A: No, it is shatterproof PET. We use a tough clear plastic that will not shatter into dangerous shards if hit by a bag or ball, making it the safest choice for schools.

Q: How many keys are provided?

A: Keys are provided for both locks. You will receive a set for each door, allowing for secure management of the contents.

Q: How is it installed?

A: Through internal fixing points. You open the doors to access the screw holes. We recommend two people for installation due to the weight and size.

Q: Can I use magnets on this board?

A: No. This is a felt pinboard designed for push pins or Velcro. If you require a magnetic surface, please view our magnetic whiteboard lockable range.
