Product Overview: The Compact Professional Tower

The Cobolt 400mm Black Storage model is designed to maximise vertical space. Occupying a footprint of just 40cm x 40cm, it allows Facility Managers to activate "dead space" next to pillars or in room corners. Despite its slim profile, it retains the rugged build quality of our larger units, featuring a dedicated steel/aluminium storage base and a full-height glass display zone. Delivered flat-packed, this lightweight yet sturdy unit can be carried by hand into difficult locations—such as spiral staircases or mezzanine floors—before being assembled into a permanent, fire-safe fixture.

Vertical Efficiency

  • Small Footprint, High Impact: Ideally sized for single-item highlighting. Use the verticality to display tall trophies, mannequin heads, or high-value electronics without taking up valuable walkway width.
  • Alcove Ready: The 400mm width is specifically dimensioned to fit into standard architectural alcoves and niches, allowing you to integrate secure display storage into the fabric of your building.

Secure & Practical

  • Dual-Zone Security: Peace of mind comes standard. The top glass door protects your display, while the bottom steel cupboard hides clutter. Both zones are keyed alike for convenience but operate independently.
  • Single Hinged Door: The reversible-style single door offers simple, direct access to the interior. It is fitted with a cylinder lock and magnetic catches to ensure a dust-tight seal when closed.

Focused Illumination

  • Concentrated Lighting: In a compact 400mm square, the integrated LED spot lighting is incredibly effective. It creates a "pillar of light" effect, focusing intense brightness on your items to draw the eye from across the room.
  • Matte Black Contrast: The black powder-coated frame frames the view tightly, removing peripheral distractions and forcing the viewer's attention solely onto the illuminated object inside.

The Cobolt Standard

  • Direct Manufacturer: We build these units to the same commercial standard as our 1.2m cabinets. You get the same fire-rated materials and toughened glass, just in a more manageable size.
  • Certified Safety: Essential for schools and public areas, this unit is tested to BS 5852 Fire Safety Standards, ensuring your "niche" display doesn't compromise your fire risk assessment.
  • Free UK Mainland Delivery: Even for smaller cabinets, shipping glass is specialist work. We cover the cost of secure pallet delivery to your door.

The 1800mm x 400mm Black Storage Cabinet is the go-to solution for "in-fill" display. It is frequently specified for Jewellery Store Corners, School Reception Alcoves, Home Collector Rooms, and Office Pillars.

Expert Advice: 400mm Black Tower Cabinets

Q: Is this compact cabinet difficult to assemble?

A: No, this is one of our easiest units to build. Because the glass panels are smaller and lighter than our wide units, it can often be assembled by a single person (though we always recommend two for safety). It arrives flat-packed with clear instructions.

Q: Is a 400mm wide cabinet stable?

A: Yes. Despite being tall and narrow, the unit is designed with a heavy, rigid base to ensure stability. It also includes adjustable feet to compensate for uneven floors. For added security in busy public areas, we recommend fixing it to the wall.

Q: What fits inside a 400mm cabinet?

A: The 400mm width is perfect for "hero" items. It accommodates single large trophies, mannequin heads, vases, or stacks of smaller boxed products. The vertical arrangement allows you to display 4-5 key items prominently without clutter.

Q: Is the door lockable?

A: Yes. Both the top glass display door and the bottom storage cupboard are fitted with secure barrel locks. Keys are included, ensuring your items remain safe in retail or school environments.

Q: Is this cabinet fire rated?

A: Yes. Like our larger models, this tower cabinet is certified to BS 5852:2006. This is essential for compliance when placing furniture in escape routes, reception areas, or educational buildings.

Q: How many shelves does it come with?

A: It comes with 3 adjustable tempered glass shelves. Because of the storage base, the glass display area is shorter than a full-height model, so 3 shelves offer the perfect spacing for standard items.

Product FAQs

Expert Advice: 400mm Black Tower Cabinets

Q: Is this compact cabinet difficult to assemble?

A: No, this is one of our easiest units to build. Because the glass panels are smaller and lighter than our wide units, it can often be assembled by a single person (though we always recommend two for safety). It arrives flat-packed with clear instructions.

Q: Is a 400mm wide cabinet stable?

A: Yes. Despite being tall and narrow, the unit is designed with a heavy, rigid base to ensure stability. It also includes adjustable feet to compensate for uneven floors. For added security in busy public areas, we recommend fixing it to the wall.

Q: What fits inside a 400mm cabinet?

A: The 400mm width is perfect for "hero" items. It accommodates single large trophies, mannequin heads, vases, or stacks of smaller boxed products. The vertical arrangement allows you to display 4-5 key items prominently without clutter.

Q: Is the door lockable?

A: Yes. Both the top glass display door and the bottom storage cupboard are fitted with secure barrel locks. Keys are included, ensuring your items remain safe in retail or school environments.

Q: Is this cabinet fire rated?

A: Yes. Like our larger models, this tower cabinet is certified to BS 5852:2006. This is essential for compliance when placing furniture in escape routes, reception areas, or educational buildings.

Q: How many shelves does it come with?

A: It comes with 3 adjustable tempered glass shelves. Because of the storage base, the glass display area is shorter than a full-height model, so 3 shelves offer the perfect spacing for standard items.
