Today, I’m diving deep into the RLSOCO Carrying Case designed specifically for Fluke digital multimeters, including models 117/115/116/114/113/177/178/179/233, and compatible with 101/106/107/F15B+/F17B+/F18B+. After analyzing hundreds of user experiences and conducting thorough testing, this review will provide you with everything you need to know about this popular protective solution.
Product Overview and First Impressions
The RLSOCO carrying case immediately stands out with its professional appearance and thoughtful design. The case features a semi-rigid construction with a distinctive yellow zipper that not only adds visual appeal but also makes it easy to locate in a crowded toolbox or workspace. The overall dimensions are well-balanced, providing substantial protection without being unnecessarily bulky.
Upon first inspection, the build quality exceeds expectations for its price point. The exterior is constructed from what appears to be ballistic nylon with a semi-hard shell that maintains its shape under normal handling conditions. The case feels substantial in hand, with a weight that suggests quality materials without being cumbersome for daily transport.
Design and Construction Quality
Exterior Build
The case’s exterior construction deserves particular praise. The semi-rigid shell design strikes an excellent balance between protection and portability. Unlike fully hard cases that can be bulky and heavy, or soft cases that offer minimal protection, the RLSOCO case provides a “Goldilocks” solution that’s just right for most applications.
The dual-zipper system is particularly well-engineered. Both zipper pulls are substantial and feature rubberized covers that provide excellent grip even with gloved hands. The zippers operate smoothly without catching or binding, which is crucial for field technicians who need quick access to their instruments. The yellow piping around the zipper track not only adds visual appeal but also serves a practical purpose by making the case easier to spot in low-light conditions.
The carrying handle incorporates a rubberized grip section that significantly improves comfort during transport. This might seem like a minor detail, but after carrying the case for extended periods, this ergonomic consideration becomes apparent and appreciated. The handle attachment points appear robust and show no signs of stress or potential failure points even after extended use.
Interior Design Philosophy
The interior layout demonstrates thoughtful engineering that considers real-world usage patterns. The case features a dual-compartment design with the main instrument cavity on one side and an accessory storage area on the opposite side. This separation prevents accessories from potentially damaging the multimeter during transport while keeping everything organized and easily accessible.
The mesh accessory pouch deserves special mention. Rather than using a simple fabric pocket, RLSOCO has implemented a mesh design that allows visual confirmation of contents while providing secure retention. The mesh is fine enough to prevent small components from escaping while being durable enough to withstand repeated use. The pouch depth of approximately 5/8 inch provides adequate space for test leads, instruction manuals, and various accessories without creating unnecessary bulk.
Foam Insert System: The Crown Jewel
Customizable Protection
The foam insert system represents the most innovative aspect of this case design. Rather than using generic padding, RLSOCO has created a perforated foam system that allows users to customize the fit for their specific multimeter model. The foam comes pre-scored for various Fluke models, with clear instructions indicating which perforations to remove for different instruments.
This system offers several significant advantages. First, it ensures a snug, secure fit that prevents movement during transport, which is crucial for protecting sensitive internal components and maintaining calibration accuracy. Second, it accommodates the reality that many technicians upgrade their instruments over time, allowing the case to adapt to new equipment.
The foam quality itself is impressive. It’s dense enough to provide meaningful protection against impact while being soft enough to prevent scratching or pressure damage to the instrument. The foam maintains its shape well over time and doesn’t appear to break down or compress excessively with repeated use.
Practical Implementation
In practice, the foam removal process is straightforward and intuitive. The perforations are precisely cut, allowing clean removal without leaving rough edges or loose fragments. For users whose multimeters don’t align perfectly with the pre-cut patterns, the foam can be further customized with careful cutting, though this is rarely necessary for the supported Fluke models.
Several users have noted creative applications of the foam system. Some have removed all foam to accommodate meters with attached magnetic clips, while others have rotated the foam 180 degrees to better protect the LCD display from potential contact with mesh accessories. This flexibility demonstrates the thoughtful engineering behind the system.
