Description
The CMC CAPTO Rope Grab – Gain the Advantage
The CMC CAPTO Rope Grab is built around an innovative V-groove Cam. This innovative design not only handles rescue loads but also provides force-limiting overload protection. In addition, the CAPTO comes in two sizes: a gray model for 10.5-11 mm rope and a red one for 12.5-13 mm rope. Both models have NFPA General Use certification. Furthermore, the 11 mm CAPTO also has EN 12841:2006/B, 567:2013, and 12278:2007 certifications.
Ultimately, the CAPTO is a compact, versatile, and easy-to-use tool. Therefore, it is well-suited for many rescue and rope access applications. It replaces multiple devices, which streamlines both your training and your operations. Thanks to its unique features and force-limiting capabilities, the CAPTO gives technicians greater safety and efficiency for hauling and ascending.
More About CAPTO
You can install the CAPTO quickly and easily on both tensioned and untensioned lines. Furthermore, you can use it with one hand. A double-action side plate protects the device from accidental opening. This feature also moves the cam out of the rope’s path to make rigging easier.
For example, both the rope grab and pulley are immediately accessible. This makes it possible to build a 3:1 haul system in a single motion. You do not need to use knots, hitches, or additional equipment. Compared to a traditional 3:1 system, the CAPTO is faster to install, lighter, and half the length.
Its compact size also maximizes your haul field and reduces the number of resets you need. In addition, adding more mechanical advantage is simple. The CAPTO smoothly progresses from a 3:1 to a 5:1 system. It works well with piggyback systems and additional CMC CAPTO Rope Grabs.
CAPTO’s components are adequately spaced to prevent ropes from rubbing against each other. The pulley is highly efficient, providing 91% raising efficiency with 11mm rope. The CAPTO also has a becket integrated directly into the pulley to promote clean rigging and efficient hauling. You can use the becket as an independent attachment point. It is ideal for attaching mechanical advantage components, lanyards, foot loops, and retention systems to prevent dropping the device. CAPTO also has a hollow cam axle for installing an accessory loop to support remote resets and device stowage. CMC offers a CAPTO Soft Shackle accessory that is strong, durable, and specifically sized for this purpose.
A key feature of the CAPTO is its force-limiting V-groove cam. Furthermore, the V-groove cam safely dissipates energy during overload situations. This design, in turn, protects your entire rope system. When a load-limiting event occurs, the V-groove Cam will reliably slip. This alerts the haul team to an issue. You should then inspect the system and identify the cause. Ultimately, you should be able to resume operations if you deem it appropriate.
In addition, the V-groove cam is gentle on the rope. Therefore, it is ideal for hauling heavy loads, taking up slack, or repeatedly ascending and down climbing. You can hold the V-groove cam open by pushing on the thumb grip. This makes it easy to collapse haul systems and adjust your position. Also, it runs along the rope with minimal friction. This allows the CAPTO to travel down towards the load in vertical environments. Finally, you can watch the Meet the CAPTO video for more information.
