Product Overview: The Traditional Square

The Cobolt 1200x1200mm Tamperproof Green Board is the ideal solution for areas requiring a large, secure display that respects a traditional environment. The Square 4ft x 4ft Format creates a balanced focal point, perfect for large walls in assembly halls or community entrances. Combined with Emerald Green Felt and a secure polycarbonate cover, it creates a protected space for information that feels established and trustworthy.

Security & Safety

  • Controlled Access: In schools and public halls, open boards can become cluttered or vandalised. This lockable unit (2 keys supplied) puts you back in control, ensuring that only authorised staff or councillors can update the display.
  • Shatterproof Glazing: We use optical-grade PET plastic for the large door panel. Unlike glass, it is impact-resistant and flexible, making it the safest option for environments with children or high footfall.
  • Tamper-Resistant Frame: The aluminium frame features a deep profile that shrouds the door edge, preventing prying and keeping the unit secure against casual interference.

Symmetrical Capacity

  • Generous Display: The 1200x1200mm interior provides ample room to display approximately 12 to 16 A4 sheets (depending on layout). It is also perfect for large square maps, art displays, or project grids.
  • Classic Aesthetic: The Green background is the standard for education and local government. It provides a calm, low-glare surface that makes reading detailed text easier on the eye.
  • Robust Engineering: A single door of this size requires strong support. Our units use heavy-duty hinges and a reinforced frame to ensure the door operates smoothly without sagging.

The Cobolt Standard

  • Free UK Mainland Delivery: Shipping large square boards involves complex logistics. We cover these costs to provide a transparent, all-inclusive price for your school or council budget.
  • British Assembly: Our tamperproof range is assembled in the UK, ensuring that every lock and hinge is tested for smooth operation before it leaves our facility.
  • Stock Availability: We hold this specialist square size in stock for rapid dispatch, helping you upgrade your displays immediately.
  • Complete Kit: Every board arrives with a secure wall fixing kit and a set of keys, allowing for immediate installation by your caretaker.

Where is this 1200x1200mm Lockable Green Board specified?

Cobolt Service & Ethos: Direct from the Experts

  • 50 Years of Heritage: We have supplied the UK education and public sectors for half a century, providing reliable, safe display equipment.
  • Built to Last: We use high-grade materials. Our large doors are supported by heavy-duty components to prevent sagging, ensuring a long service life.
  • In-House UK Support: Need advice on installation space? Our UK-based team is available to ensure this large unit fits your requirements.
  • Project Expertise: Whether equipping a single hall or a nationwide network of centres, we have the stock and logistics to deliver.

Designed for Public Environments.

  • Impact Safety: The door panel is made from PET, a plastic that is significantly tougher than glass. It will flex upon impact rather than shattering, making it the essential choice for areas with high footfall or children.
  • Tamper Resistance: The frame is designed with tight tolerances, making it difficult to pry open without the key. This ensures your official notices remain the authoritative source of information.
  • Durable Surface: The Green felt is bonded to a high-density core. It grips pins firmly and the dark colour helps to hide pinholes, keeping the board looking smart for years.
  • Secure Mounting: The unit is fixed to the wall via internal holes accessible only when the door is unlocked. This prevents the entire board from being stolen.
  • We offer a 1-year manufacturer's guarantee covering the lock mechanism, hinges, and frame integrity.

Expert Advice for Large Tamperproof 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: How much space do I need to open it?

A: Allow for a 1.2m swing. As this is a large square unit with a single door, you need approximately 1.2 metres of clearance in front of the board to open the door fully to 90 degrees.

Q: How many A4 sheets does it hold?

A: Approx 12-16 A4 sheets. Depending on your spacing, you can fit a grid of 4x4 sheets, though 4x3 offers a more spacious layout with headers.

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 schools and community halls.

Q: How many keys are provided?

A: Two keys are included. This allows for a master key to be kept in the office and a spare for the user updating the board.

Q: Can I use magnets?

A: No, this is a felt pinboard. You must use standard push pins or Velcro to attach your documents. We do sell magnetic versions separately.

Q: How is it installed?

A: Through internal fixing points. The screw holes are located inside the case (accessible only when open), which hides the fixings and prevents theft of the unit once locked.

Q: Why choose the Green version?

A: Green is the traditional choice. It creates a calming, authoritative backdrop for information, making it the preferred choice for schools and parish councils.

Q: How much space do I need to open it?

A: Allow for a 1.2m swing. As this is a large square unit with a single door, you need approximately 1.2 metres of clearance in front of the board to open the door fully to 90 degrees.

Q: How many A4 sheets does it hold?

A: Approx 12-16 A4 sheets. Depending on your spacing, you can fit a grid of 4x4 sheets, though 4x3 offers a more spacious layout with headers.

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 schools and community halls.

Q: How many keys are provided?

A: Two keys are included. This allows for a master key to be kept in the office and a spare for the user updating the board.

Q: Can I use magnets?

A: No, this is a felt pinboard. You must use standard push pins or Velcro to attach your documents. We do sell magnetic versions separately.

Q: How is it installed?

A: Through internal fixing points. The screw holes are located inside the case (accessible only when open), which hides the fixings and prevents theft of the unit once locked.

Q: Why choose the Green version?

A: Green is the traditional choice. It creates a calming, authoritative backdrop for information, making it the preferred choice for schools and parish councils.
