Rope Logic's Fiddle Block Kit

Rope Logic's Fiddle Block Kit
Item #: SET81
$379.00
An ideal accessory to the Portawrap that allows the user to pretension lines, create lift or simply remove slack from systems with lots of rope in between. Fiddle blocks provide a very compact, in-line system for incredible 4:1 pulling force, that 400-pounds of result to 100-pounds of force. Steel carabiners and prusik are for attaching blocks to line and anchorage.

Description

Details

These high-strength blocks are ideal for pre-tensioning lines or lifting heavy objects. Fiddle blocks are easier to deploy than our tree pulling kit (especially for beginners) because the system is applied on top of a host line instead of involving threaded host line. Fiddle blocks are generally stored fully rigged so that you simply attach the ends to host line (via the included Prusik) and anchor (a tree, vehicle, or even host rope again, using the included carabiner on your sling or other means). The fiddle block’s limitations are that it’s tlimited to 10 feet of working spread with the included (50-foot) rope; a friction device (like Portawrap) is required to hold drawn rigging line for multiple advances; and the standard package is slightly bulkier than the tree-pulling kit.

The drawing (below) demonstrates how pulling with 200 pounds of force results in a 5:1 mechanical advantage (1,000 pounds) of lift. Between pulls, a built-in cleat holds position on the line, which can be released with a snap of the wrist. Combine this kit with a Portawrap or other lowering device for the ultimate in compact power!

Kit includes two blocks, 50 feet of half-inch line with spliced eye, two steel carabiners & rigging prusik.

1000# working load limit. This would be very easy to exceed with a 4:1 pulley.
Great little system with an efficient capture, but probably best suited for cabling, not pulling trees.
Check out several other systems with 25-50kn limits for actual rigging applications.
It would be nice if all of the fiddle block systems were rated and grouped in a uniform chart showing block capacities. (Posted on 3/7/2017)

Great product! Quick easy and when combined with a porta wrap you can pull over anything. Only issue it's the brake not grabbing sometimes. (Posted on 11/17/2016)

I can build my own leverage systems, but the quick assembly, and auto brake make pulling something over very easy. You probably save 1/2 the time of building a 5:1 leverage system, but the hardware wouldn't allow for massive loads. (Posted on 2/17/2014)
