Description

Details

The ROOK can be used as a prusik minding pulley, on a lanyard or flipline, on a rope bridge, or even as a redirect. Conceptualized and designed by SHERRILLtree staff member Brandon Nance and made by world class manufacturer Rock Exotica in the USA. 28kN.

Arborists began to see the functionality of small pulleys integrated into climbing systems some time ago. What started out as using whatever was available has developed into a full-blown category of must-have micro pulleys.

The latest entry into this unique class is the vision of devoted climber and passionate SHERRILLtree employee Brandon Nance, brought to life by Rock Exotica: the Rook.

Made for lines up to a half-inch. An intrinsic swivel is designed for any situation to maintain whatever alignment you require. Three connection points turn this into a tool of many options and uses. Use on a rope bridge, or as a prusik-minding pulley, or on a lanyard/flipline, or even as a redirect. The possibilities are yours to discover.

Quality construction, smooth operation... Review by Jeff Guenter

This pulley uses ball bearings throughout and is precision machined... holding it in your hand, it is compact with enough weight not to feel like Tinkertoy technology. Reduces both line twist and friction when used at either (or both) ends of the climbing system. Neutral colors work well with almost any color scheme if, like me, you use separate schemes for each rope system employed. Personally, I like the tight fit of the 'biners in the attachment holes. This is a product worth budgeting for as you plan your climbing systems, especially if you're picky about the details and want the most bang for your buck. (Posted on 11/4/2014)
worth perfecting Review by samuel luria - arzei arbor

As a 3 year user of the DMM 3-point pulley on my bridge, (not "meant" for that) and finding only one drawback : the need to constantly tend to the proper and safe alignment of three carabiners in a single flat plane, to avoid bilateral stress on the pulley, I DREAMT of a swivel solution. Now my dream has been somewhat fulfilled, especially with Rock being the one to bring this to market. Who better to trust with your life and limb?( no offence to the good people of Wales) ... but... the "cross loading", of the 'biners themselves, has been WAY overcompensated for. Period. Lose the o-rings, and make the holes BIGGER. Please. Thanks to Rock and Sherrill! (Posted on 12/11/2013)
Much less friction as a bridge device. Review by Jason Gillespie

I've been using the rook strictly as a bridge pulley with my other Sherrill product, their Edge Saddle. I can say that for sure that it isn't really necessary, rings work just fine. I personally find it advantageous to have the paw style tie in point on my bridge. I encounter far less getting pulled every which way when transferring between my lanyard and main system. I also like the swivel when climbing DRT, it's nice to take out twists in the system without spinning and pulling the ends apart. I also have adjusted to the ease with which I can rotate side to side now having the pulley in place of a ring... it took some getting used to.All in all I'd rate this as a luxury item. I have it and I'll definitely keep using it. Is it necessary? ....nah.I cannot imagine using this in place of a hitch climber... yes, it would work, but the HC is a much better design for that particular application in my humble opinion, being midline attachable.I am glad they had them produced through Rock Exotica, it is a high quality piece.

Great Bridge Connection Review by Todd Gesshe

This a smooth little piece of gear for your rope-style bridge. Particularly useful for doubled rope technique (as an alternative to the hitch-climber pulley), it separates both legs of line nicely, and the swivel means no more line twists. I'm diggin it! Warning: the attachment holes are somewhat small and though great for eliminating sideloading, it should be mentioned that many biners won't fit. DMM ultra O and Shadow fit nicely.
