The Uchida UBO-105E envelope-slot variant is suited to cash-handling businesses that need envelope deposits, 52.5 L capacity and programmable digital access. It measures 670 H × 500 W × 470 D mm, weighs 105 kg and includes an anti-fishing envelope slot, one top lockable drawer and one adjustable shelf. Buyers should confirm that the delivery route and final position can accommodate its size and weight.

The envelope slot allows authorised staff to deposit envelopes without opening the main safe door. Deposits should be appropriately sized and must not obstruct the slot or internal fittings. This model also includes an anti-fishing mechanism designed to deter retrieval through the slot.

Fire protection is limited due to the envelope slot. The slot changes the cabinet construction, so the UBO-105E envelope-slot variant should not be presented as providing the same two-hour protection as the corresponding non-slot model; an exact duration is not stated for this variant.

The UBO-105E envelope-slot variant uses a programmable digital lock with an optional key lock; it can be locked with the key or used without engaging the key lock. Keep every operational or override key secure and separate from the safe, and restrict combinations or codes to authorised users.

It has removable castors, stands 610 mm high without them, and has no mounting hole.
