Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in Review

The Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in: A Review After Real Use

For anyone who relies on their equipment to perform flawlessly in demanding environments, the name RAM Mounts often sparks a sense of confidence. After years of navigating everything from salt-laden marine decks to dust-choked workshop benches, I’ve come to appreciate gear that doesn’t just survive, but thrives. It was a recurring frustration with securing sensitive electronics – my GPS unit on a perpetually bumpy boat ride, a powerful work light in the dimly lit corners of my fabrication shop – that finally led me to seek a more robust solution. The common, flimsy clamps and basic suction cups just weren’t cutting it, often vibrating loose or failing entirely when I needed them most. I considered some generic, off-brand articulating arms, but their uninspiring materials and vague specifications immediately raised red flags. My first impression of the Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in was one of solid, no-nonsense engineering. It felt substantial, a far cry from the plastic toys that often pass for mounts.


Real-World Testing: Putting Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in to the Test

First Use Experience

My initial deployment for this double socket arm mount was on my fishing boat. I needed a stable platform for my fish finder that could withstand the constant jarring of waves and spray, and also accommodate a secondary device, like a marine radio or a spotlight. The included 2.5″ diameter round base was surprisingly adaptable, finding a secure spot on a vertical bulkhead with minimal fuss. The articulating nature of the arm, controlled by the T-handle grip on each socket, allowed for precise positioning, which is crucial for optimal screen visibility and easy access to controls.

During a particularly choppy outing, the mount held its ground remarkably well. The unit, rigged with both my GPS and a powerful LED spotlight, barely registered the significant hull pounding. I did notice a slight, almost imperceptible, settling of the arm after about an hour of continuous vibration, but a quick twist of the T-handle grip restored the firm hold without any tools. This initial experience was significantly more reassuring than any other mounting system I’d used previously on the water.

Extended Use & Reliability

Over the past six months, this RAM mount has become a constant fixture, migrating between my boat, my workshop, and even my off-road vehicle. On the boat, it’s endured countless hours of direct sunlight, saltwater spray, and temperature fluctuations without any visible degradation. The rubber balls remain pliable, and the sockets maintain their firm grip, even after being adjusted dozens of times.

In the workshop, it’s served to position a high-intensity inspection lamp over intricate fabrication work. Here, it’s faced airborne metal dust and occasional accidental bumps from tools or materials. The 1.5″ rubber ball system, combined with the sturdy rectangular plate, has shown no signs of wear; there are no cracks in the plastic components, nor any loosening of the hardware. This unit has definitely outperformed many of the cheaper alternatives I’ve tried in the past, which often develop play or loosen over time.

Maintenance has been virtually non-existent. A quick wipe down with a damp cloth is usually all that’s needed to remove dust or grime. I haven’t encountered any stiffness or corrosion, which is a testament to the quality of materials and construction RAM Mounts employs. It truly feels like a set-it-and-forget-it kind of component, which is exactly what you want when dealing with critical equipment.

Breaking Down the Features of Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in

Specifications

The core of this mounting system is its robust construction, centered around a 1.5-inch rubber ball system, which provides a significant amount of articulation and strength. The double socket arm is the key component, allowing for a wide range of motion and adjustability. This particular model features a 2.5″ diameter round base, designed for secure mounting on curved or flat surfaces, often found on marine vessels. Attached to this is a 11″ x 3″ rectangular plate, offering ample space to attach various devices.

The 1.5-inch ball size is crucial here, as it provides a much stronger connection and greater load-bearing capacity compared to smaller 1-inch ball systems. The dual socket design allows for independent adjustment of each end of the arm, enabling precise positioning of two separate items or a single item with complex orientation needs. The inclusion of end caps with a “T” handle grip on the sockets is a practical touch, offering a secure and comfortable way to tighten and loosen the arm without needing tools.

Performance & Functionality

In practice, the Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in excels at its primary function: securely holding and positioning equipment. The 1.5-inch ball and socket system creates an incredibly stable mount. Once tightened, the arm holds its position steadfastly, even under significant vibration and stress. I’ve used it to mount a fairly heavy 7-inch GPS unit and a compact, but powerful, LED spotlight simultaneously, and neither showed any tendency to sag or shift.

The standout strength of this mount is its adjustability and stability. The ability to independently lock down each socket means you can dial in the exact angle and orientation you need, and it will stay there. The primary weakness, if one could call it that, is that with extreme torque applied to the T-handle grip, the plastic can feel like it’s nearing its limit, though I’ve never actually had one fail. For its intended purpose, it performs exceptionally well, exceeding the capabilities of many lighter-duty mounting solutions.

Design & Ergonomics

The design philosophy behind RAM Mounts is clearly centered on rugged functionality. The materials used – a combination of high-strength composite and durable rubber for the balls – feel built to last. The finish is typically utilitarian, with a matte texture that resists glare and fingerprints.

Ergonomically, the T-handle grips on the sockets are a brilliant addition. They provide excellent leverage for tightening, even with wet or greasy hands, and are comfortable to operate. The overall assembly feels robust and well-engineered, with no superfluous parts. The rectangular plate offers a good surface area for drilling additional mounting holes if needed, making it highly customizable.

Durability & Maintenance

Given its construction and my own experiences, the Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in is built for long-term durability. I expect this unit to last for many years, even with regular exposure to the elements. The composite materials are highly resistant to UV degradation and corrosion, which is a major plus for marine or outdoor applications.

Maintenance is minimal, as mentioned before. The rubber balls might eventually show some signs of compression or wear after years of heavy use, but this is a common characteristic of ball-and-socket mounts and is generally not a critical failure point. Replacement balls are readily available if needed. The most important thing to remember is to avoid overtightening to the point of stripping the threads within the socket, though the design makes this difficult to do accidentally.

Accessories and Customization Options

While the Ram Mounts RAM-137 Double Socket Arm Ball Mount 1.5in is a complete mounting solution on its own, its true strength lies in its compatibility with RAM Mounts’ extensive ecosystem. The rectangular plate itself is designed to be drilled and attached to a variety of bases or directly to equipment. RAM offers a vast array of compatible bases, from standard bolt patterns to vehicle-specific mounts.

Furthermore, the other end of the arm can accept any RAM Mounts device holder – whether it’s for a specific GPS model, a universal phone clamp, or a camera adapter. This versatility means that as your equipment needs change, the core mounting arm can remain the same, simply swapping out the end device holder. The 1.5-inch ball size ensures compatibility with a wide range of their heavier-duty device holders.
