Learn step-by-step how to set up and operate the NAR Rope Grab Pulley SPOC for efficient rope rescue. Avoid common mistakes with our practical guide.

Quick Answer

Use the NAR Rope Grab Pulley SPOC as a combined ascent and positioning tool by attaching it to your harness, locking the rope grab at your working height, and using the pulley for controlled descent or load movement.

Why the SPOC Design Matters for Rescue

The Rope Grab Pulley SPOC integrates a rope grab and pulley into a single unit, reducing the number of components you need to manage on rope. This streamlined design helps you switch between ascending, holding position, and descending without swapping gear—saving time in time-critical rescue scenarios.

Limitations to Consider

Because the SPOC combines two functions, it is not as specialized as a dedicated rope grab or a standalone pulley. For very high-load mechanical advantage systems, a separate pulley may offer smoother operation. The SPOC is best suited for personal positioning and light load handling rather than heavy hauling.

Step-by-Step: Using the NAR Rope Grab Pulley SPOC

1. Inspect and Attach: Check the SPOC for cracks, wear, or debris. Attach it to your harness via a locking carabiner through the integrated attachment point. Ensure the rope grab mechanism faces upward when ascending. Common mistake: attaching upside down, which prevents the grab from engaging properly.
2. Load the Rope: Open the rope channel and insert the rope. Close and secure the channel. The rope should run freely through the pulley side when not loaded. Verify the rope size matches the SPOC specifications (typically 10–13 mm). Checkpoint: rope must move freely in the pulley before applying weight.
3. Ascend and Lock: Pull down on the rope below the SPOC to ascend. The rope grab will automatically lock when you stop pulling. To hold position, simply stop pulling—the grab engages without manual locking. Common mistake: over-pulling after stopping, which can cause the grab to slip if the rope is slack.
4. Descend or Lower: To descend, lift the rope grab release lever while maintaining tension on the rope below. Control your descent speed by gradually releasing the lever. For lowering a load, attach the load to the pulley side and use the rope grab as a progress capture. Checkpoint: always keep a hand on the rope below the SPOC during descent to avoid a free fall.
5. Dismount and Store: Once on the ground, remove tension from the SPOC, open the rope channel, and slide it off the rope. Rinse with fresh water if exposed to dirt or salt, and store in a dry, cool place away from direct sunlight. Common mistake: storing wet or dirty, which accelerates wear on the cam and bearings.
