Portable Safe From Master Lock 5900D

Compact and Secure Storage On the Go

The Master Lock 5900D is built to protect small valuables such as mobile phones, wallets, keys, passports, and jewellery. It is compact enough to fit into a backpack or gym bag, while being tough enough to deter theft and tampering.

The outer case is made from impact-resistant ABS plastic with an internal foam lining to protect delicate contents from scratches and movement. The 5900D is water-resistant and suitable for use indoors or outdoors.

Perfect for Leisure and Travel

The Master Lock 5900D is a popular choice among travellers and active users. Whether you're spending the day at the beach or using a hotel locker, the integrated cable allows the safe to be anchored securely to fixed objects such as bed frames, benches, or inside lockers.

With enough space to hold essential items, it allows you to move freely without the worry of leaving valuables unprotected.

Ideal for Workplace and Gym Environments

Many employers, contractors, and gym users carry small but high-value personal items such as mobile phones or car keys. The 5900D provides secure temporary storage in environments where larger lockers may not be available.

It fits easily inside a standard locker, and the combination lock ensures that users do not need to carry additional keys.

Set-Your-Own Combination

The 5900D uses a 4-digit resettable combination lock, allowing each user to choose their own code. This adds a layer of customisable security while eliminating the need for physical keys, which can be lost or duplicated.

Resetting the code is a simple process and can be done as often as needed, making it suitable for shared use or frequent travellers.

Lightweight and Durable

Weighing less than 1 kilogram, the 5900D is light enough to carry comfortably while offering robust protection. Its outer shell resists scratches and impact, while the inner foam cushions valuables during transport.

The safe measures approximately 23cm x 13cm x 6cm, offering ample internal space for essential items without bulk.

Water-Resistant and Weather Ready

With a sealed edge design, the Master Lock 5900D protects against light rain, splashes, and humid environments. While not fully submersible, it offers a level of protection that is ideal for poolside use, beach days, or sports facilities with wet areas.

This makes it an excellent choice for leisure centres, swimming clubs, or any environment where moisture is a concern.

Applications and Use Cases

• Travellers protecting passports and documents
• Gym users securing phones and keys during workouts
• Students in shared accommodation
• Holidaymakers storing items in caravans or tents
• Temporary on-site workers storing ID cards and small electronics
• Day trips and outdoor events

Its versatility makes the 5900D a staple for those needing portable, personal security.
