Plastic security monitoring power supply waterproof box instrument enclosure F4B-1 model ABS material 100x68x40 mm dimensions for custom processing and other shell applications
F4B-1 ABS Plastic Waterproof Instrument Box for Security Monitoring and Power Supplies

This F4B-1 model waterproof box is a purpose-built enclosure crafted from ABS plastic, designed to house and protect sensitive electronic components such as security monitoring system power supplies and related instrumentation. With external dimensions of 100mm in length, 68mm in width, and 40mm in height, it offers a compact solution for installations where space is at a premium. The product is noted for being suitable for custom processing, meaning it can be adapted—through drilling, cutting, or other modifications—to fit specific wiring layouts, mounting brackets, or component sizes, providing flexibility for integrators and installers. Its stated scope of application extends beyond a single use case to serving as a protective shell for various other electronic devices, making it a versatile choice for different projects.
Features and Construction

The enclosure is defined by its specific model number, material choice, and dimensions, which combine to form its core identity and utility.
Material and Build
Constructed from ABS (Acrylonitrile Butadiene Styrene) plastic, this box provides a balance of strength, rigidity, and light weight. ABS is a common thermoplastic polymer known for its good impact resistance and dimensional stability, making it a practical choice for protective enclosures that may be mounted in various environments. The material itself contributes to the product's role as a waterproof instrument box, though the specific ingress protection (IP) rating is not detailed in the source text.
Size and Practical Fit
The box measures 100mm by 68mm by 40mm. These dimensions define the external footprint and internal capacity available for housing components. This specific size makes it suitable for compact power supplies, small circuit boards, terminal blocks, or monitoring system modules that require environmental protection. The proportions are a key differentiator for installers selecting an enclosure that will fit into a particular space or alongside other equipment.
Uses and Placement

Its application is centred on providing a sealed, protective environment for electronics, with flexibility noted in the source information.
Event or Professional Use
In professional security and monitoring installations, this box can house the power supply unit that provides stable voltage to cameras, sensors, and control panels. By enclosing these components, it helps guard against dust, moisture, and accidental physical contact, which can improve system reliability. The option for custom processing is particularly relevant here, allowing professionals to create precise cable entry points, ventilation holes, or mounting points tailored to the job's specific wiring diagram and hardware.
Everyday Home Use
For DIY electronics enthusiasts or homeowners installing basic monitoring systems, this box offers a neat and protected way to contain wiring junctions, small transformers, or timers. Its modest size makes it suitable for discreet placement in lofts, garages, or under eaves where monitoring equipment is often located. The ability to modify it means a hobbyist can adapt it for non-standard projects, such as creating a housing for a weather sensor or a custom lighting controller.
Benefits and Buying Value

The value of this product lies in its defined specifications, material choice, and the flexibility explicitly mentioned in the source text.
Reuse and Low Maintenance
As a simple plastic enclosure with no moving parts, it requires virtually no maintenance once installed. The ABS plastic is resistant to many common chemicals and does not corrode, contributing to a long service life in typical indoor or sheltered outdoor environments. Its generic 'other shell' application scope suggests it could be repurposed for different projects over time, adding to its utility.
Why Choose This Product
Choosing the F4B-1 model is a decision based on its concrete specifications: you require an ABS plastic enclosure with dimensions very close to 100x68x40mm, and you value the option to customise it. It is a match for searches seeking a specific-sized waterproof box for instrumentation. It provides a factual, no-frills solution where the dimensions, material, and model number are the primary guides for selection, rather than unsupported claims about performance or durability.
