Let’s Dive into ISC Double Prusik Pulley
The ISC Double Prusik Pulley is a heavy-duty piece of equipment designed for demanding applications. It’s manufactured by ISC Wales, a company known for its robust and reliable climbing and rescue gear. This pulley aims to provide smooth and secure operation in systems where Prusik hitches are used for controlled ascent or descent.
What brought me to the ISC Double Prusik Pulley was a need for a more reliable and efficient pulley system for tree climbing and rigging. My old pulley was struggling with heavier loads, causing excessive wear on my ropes and making controlled descents difficult. I was looking for something that could handle the strain of professional tree work while being smooth and dependable.
Unboxing the ISC Double Prusik Pulley, my initial thought was, “This thing is built like a tank.” The aluminum construction felt incredibly solid, and the weight (17.6 oz) suggested durability without being overly cumbersome. The red anodized finish looked professional and added to the sense of quality craftsmanship.
Compared to my previous single-sheave pulley and a lighter micro pulley, the ISC Double Prusik Pulley stood out due to its double sheave design and Prusik-minding capabilities. I considered a similar pulley from Petzl, but the ISC offered a higher load rating for a similar price, which was a deciding factor for my application. The load-rated becket was also a significant plus.
My first impression was excitement mixed with a bit of anticipation. The ISC Double Prusik Pulley looked like it could handle anything I threw at it, but I was eager to see how it performed in the field. I was hopeful that it would significantly improve the efficiency and safety of my climbing and rigging systems.
Real-World Testing: Putting ISC Double Prusik Pulley to the Test
First Use Experience
I first tested the ISC Double Prusik Pulley during a tree removal project in a residential area. The project involved lowering large limbs safely to avoid damaging the surrounding property. I used the pulley as part of a rigging system with a Prusik hitch for controlled descent of the cut branches.
The ISC Double Prusik Pulley performed exceptionally well in dry conditions. It handled the weight of the limbs smoothly, and the Prusik hitch engaged predictably, allowing for precise control of the descent. The large becket made it easy to attach and rotate my carabiners as needed.
Using the pulley was intuitive. I already had experience with Prusik hitches, so integrating the ISC Double Prusik Pulley into my existing system was straightforward. The design of the pulley made it easy to feed the rope and manage the Prusik cord.
The only surprise after my first use was how much smoother the descent was compared to my previous pulley. The difference was noticeable, and it made the entire rigging process more efficient and less strenuous. The pulley inspired confidence.
Extended Use & Reliability
After several months of consistent use, the ISC Double Prusik Pulley has proven to be incredibly durable. It has withstood numerous tree removal projects, exposure to various weather conditions, and the constant strain of heavy loads. There are minimal signs of wear and tear.
The anodized finish has held up well, with only minor scratches. The sheaves still spin freely, and the tamper-proof rivets remain secure. The pulley has demonstrated impressive resilience.
Maintenance is simple. I occasionally clean the pulley with a brush and mild detergent to remove dirt and debris. I also lubricate the sheaves with a dry lubricant to maintain smooth operation. The ease of maintenance helps ensure longevity.
Compared to my previous pulley, the ISC Double Prusik Pulley is a significant upgrade. It outperforms my old pulley in terms of load capacity, smoothness, and durability. It has become an indispensable part of my rigging system.
