Product FAQs

Product Overview: The Architectural Square

The Cobolt 1200x1200mm Tamperproof Grey Board is the definitive choice for modern facility management. The Square 4ft x 4ft Format creates a balanced, gallery-style focal point, perfect for large reception walls or open-plan hubs. Combined with Neutral Grey Felt and a secure polycarbonate cover, it creates a protected space for information that looks like a permanent architectural fixture rather than a temporary addition.

Secure Elegance

  • Controlled Access: In high-end developments and offices, maintaining a tidy appearance is key. This lockable unit (2 keys supplied) prevents the clutter of unauthorised fly-posting, ensuring only approved management notices are displayed.
  • 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 busy lobbies where luggage or equipment might bump the board.
  • Tamper-Resistant Frame: The aluminium frame features a deep profile that shrouds the door edge, preventing prying and keeping the unit secure against interference.

Modern 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 displaying large square architectural plans or mood boards.
  • Neutral Aesthetic: The Grey background is the standard for modern design. It provides a professional, non-distracting surface that works well with concrete, glass, and white office interiors.
  • 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 over time.

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 procurement budget.
  • British Assembly: Our tamperproof range is assembled in the UK, ensuring that every lock, hinge, and corner joint meets our high standards before dispatch.
  • Stock Availability: We hold this specialist square size in stock for rapid dispatch, helping you complete your office or lobby fit-out without delay.
  • Complete Kit: Every board arrives with a secure wall fixing kit and a set of keys, allowing for immediate installation by your facilities team.

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 busy public zones.

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 Grey version?

A: Grey is the modern standard. It creates a sleek, professional backdrop for information, making it the preferred choice for architects, new-build apartments, and corporate HQs.

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 busy public zones.

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 Grey version?

A: Grey is the modern standard. It creates a sleek, professional backdrop for information, making it the preferred choice for architects, new-build apartments, and corporate HQs.
