Product Overview: The Executive Standard

The Cobolt 2400x1200mm Tamperproof Grey Board is the definitive solution for managing large-scale information in modern buildings. Stepping up to the 8ft x 4ft Twin-Door Format, this unit provides the capacity to display approximately 24 sheets of A4 paper side-by-side. The Neutral Grey interior creates a professional "display case" aesthetic that respects the design of your building while keeping contents secure.

Twin-Door Practicality

  • Structural Engineering: Spanning 2.4 metres, a single door would be heavy and dangerous in a busy lobby. We utilise a Double Door System with a central support bar. This keeps the doors lightweight, aligned, and safe to open without obstructing the corridor.
  • Dual Locking: Each door operates independently with its own key lock. This allows you to segregate information—for example, keeping "Permanent HR Policies" locked on the left, whilst updating "Weekly Company News" on the right.
  • Shatterproof Safety: We use optical-grade PET plastic for the glazing. It is tough, flexible, and impact-resistant, ensuring it will not shatter into dangerous shards if bumped by luggage or equipment.

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 comprehensive statutory information, insurance certificates, and large site maps without clutter.
  • Modern Aesthetic: The Grey felt background is favored by architects and facility managers. It hides dust and pin marks better than traditional colours and provides a neutral backdrop that doesn't clash with corporate branding.
  • 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 procurement 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 large format board, ready for immediate dispatch to help you standardise your displays across multiple sites.
  • Complete Kit: Every board arrives with a secure wall fixing kit and keys, giving your facilities team everything they need for a secure installation.

Where is this 2400x1200mm Lockable Grey Board specified?

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

  • University Departments: A secure space for exam results, departmental news, and lecture schedules in busy modern buildings.

  • 50 Years of Heritage: We have supplied the UK commercial sector for half a century, understanding the need for reliable, safe display equipment.
  • Safety First: We prioritise safety. Our shatterproof doors and secure locks help you meet compliance obligations while protecting staff and visitors.
  • 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 lobby or a nationwide portfolio, we have the stock and logistics to deliver.

Designed for Professional Environments.

  • Impact Resistance: The PET glazing is designed to withstand the knocks of a busy corridor. 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, reception areas, 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 structurally unstable. 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), providing massive capacity for corporate information.

Q: Why choose the Grey version?

A: Grey is the modern standard. It creates a sleek, professional backdrop that is preferred in architects' studios, new-build apartments, and corporate headquarters.

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, making it safe for busy public waiting areas.

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 replace the felt if it gets damaged?

A: No, the felt is bonded. The felt surface is bonded to the core during manufacturing for durability. It is not designed to be replaced, but it is hard-wearing and resists wear.
