At Knox Safe Custody, our Size F Safe Deposit Box offers offers exceptional capacity for clients who need a secure home for extensive collections, substantial bullion holdings, or large-format documents and valuables. This box is housed in our climate-controlled, specialist vault in Houghton, Johannesburg. Every Knox safe deposit box includes R1 million in insurance cover as part of the rental fee. Clients can purchase additional cover to increase the total insured amount to a maximum of R5 million per box. All cover is subject to the applicable policy’s terms, conditions, limits and exclusions.

This size is ideal for storing:

• Large jewellery cases, multiple watch boxes, and curated heirloom collections
• Significant bullion holdings, bar boxes, coin sets, and monster boxes
• Binders, property files, legal archives, and extensive family documentation
• Art portfolios, certificates, archival material, or rare collectibles
• Hard drive arrays, digital storage systems, and comprehensive backup kits

Size F is the preferred choice for clients who value both capacity and discretion — providing a secure, private, fully insured environment built for long-term preservation. It offers exceptional space without compromising the refined, professional custodial care that sets the Knox vault apart.
