Cathedral Deed Box - A4 Fire and Waterproof - Black

The internal dimensions (H 9.4 x W 33.3 x D 21.6 cm) represent the usable space inside the box, while the external dimensions (H 16.6 x W 40.7 x D 32 cm) include the thickness of the box material and the lock mechanism.

The box is designed for A4 documents. A3 documents would likely need to be folded significantly to fit within the internal dimensions.

Two keys are provided with the deed box: one for regular use and one spare key.

This means the box is designed to protect its contents from ignition and significant damage for up to 30 minutes when exposed to external temperatures reaching 840°C.

The box is rated waterproof for up to 8 hours when submerged in up to 33cm of water. It is designed for protection against leaks, spills, and temporary submersion, not prolonged indefinite submersion.

The deed box weighs 12.8kg.

Yes, while designed for documents, it can be used to secure small valuables like jewelry or cash. However, its primary security feature is protection against fire and water, not high-level physical security against theft.

Lubricate the lock mechanism with a small amount of graphite powder. Avoid using oil-based lubricants, which can attract dust.

Verify that the lid was fully closed and latched. Inspect the rubber seal around the lid for any tears, damage, or obstructions. Ensure the seal is clean and properly seated.

While the box protects from direct flame and extreme heat, a small amount of residual moisture can occur due to the intense heat. Ensure documents are fully dried before storing them again. This is a normal characteristic of fire-resistant products.
