Plastic security monitoring power supply waterproof box with ABS material casing and compact dimensions of 100mm x 68mm x 40mm for housing electronic components and outdoor equipment protection
F4B-1 ABS Plastic Waterproof Box for Security Monitoring and Power Supply Housing

This F4B-1 model waterproof instrument box provides a fundamental protective casing for electronic components, specifically noted for use with security monitoring equipment and power supplies. Its primary function is to offer a customisable, rigid enclosure that shields sensitive circuitry from dust, moisture, and minor physical contact in various installation environments. Manufactured from ABS plastic, the box is designed for practicality in applications where a standard, compact shell is required, and it is explicitly listed as suitable for use with other shell systems, allowing for integrated setups. The dimensions are clearly defined, making it easy to assess fit for your specific components before purchase or custom processing.
Features and Construction

The box is defined by its material choice and precise dimensions, which dictate its application and limitations. It is a basic enclosure solution focused on providing a secure outer shell rather than advanced, specialist protection.
Material and Build
The casing is made from ABS (Acrylonitrile Butadiene Styrene) plastic. ABS is a widely used thermoplastic polymer known for its good impact resistance, rigidity, and dimensional stability. In the context of an instrument box, this translates to a sturdy shell that can withstand typical handling and provide a barrier against everyday environmental factors. It is not inherently waterproof to a specific ingress protection (IP) rating unless specified through custom processing, such as adding gaskets or seals.
Size and Practical Fit
The external dimensions are 100mm in length, 68mm in width, and 40mm in depth. This compact size makes it suitable for housing smaller power supply units, control boards, or monitoring system modules. The internal space is naturally smaller than these external measurements, so it is important to check the dimensions of the components you intend to house. The box's design for use with "other shells" suggests it can be mounted alongside or within larger enclosure systems, offering flexibility in more complex installations.
Uses and Placement

This product serves a clear function in protecting electronic hardware. Its applications are guided by its size, material properties, and the option for customisation.
Event or Professional Use
In professional or commercial settings, such as security system installations, this box can be used to house the power supply unit or secondary electronic controllers for CCTV cameras or access control systems. Its suitability for custom processing means installers can request specific cut-outs for cables, switches, or ventilation, tailoring it precisely to the job's requirements. The ability to integrate with other shells makes it useful for creating modular, layered protection for different system components within a single rack or cabinet.
Everyday Home Use
For DIY enthusiasts or home workshops, this enclosure can protect small project power supplies, Arduino boards, or sensor units used in home automation. Its ABS construction provides adequate protection for benign indoor environments like a garage, shed, or under-stairs cupboard. The compact size allows for discrete placement near the equipment it is protecting without occupying excessive space.
Benefits and Buying Value

The value of this product lies in its specificity and potential for adaptation. It is a focused tool rather than a generic container.
Reuse and Low Maintenance
As a simple plastic enclosure, it requires virtually no maintenance. If not permanently altered during custom processing, it could potentially be reused for different projects by fitting new components. The durable ABS material is resistant to corrosion and can be wiped clean if necessary, supporting long-term use in stable environments.
Why Choose This Product
You would select this F4B-1 box if you need a precisely sized (100x68x40mm), rigid plastic enclosure that is available for custom modification. Its stated application for security monitoring and power supplies, along with compatibility with other shells, makes it a relevant choice for those specific technical or installation scenarios. It offers a straightforward, no-frills solution where the primary need is a basic protective casing of known dimensions.
