At Knox Safe Custody, our Size E Safe Deposit Box provides a spacious, secure environment for clients needing room for larger collections, bulkier valuables, or multiple categories of items stored together. Situated within our climate-controlled vault in Houghton, Johannesburg, every Size E box includes R1 million cover at no extra cost. You can increase it to R5 million.

This size is ideal for storing:

• Larger jewellery cases, multi-watch boxes, and heirloom sets
• Substantial gold or silver bullion holdings, including bar boxes or coin collections
• Estate planning files, property portfolios, bound documents, and archival records
• Collectibles, family albums, graded coins, certificates, or heritage items that need careful preservation
• Digital storage kits, hard drives, and organised backup systems

Size E is an excellent choice for clients seeking a balance of capacity and discretion — offering enough space to accommodate a wider variety of assets while maintaining the privacy, professional oversight, and quiet confidence that define the Knox vault experience.
