A quality-manufactured pulley is the heart of a good doubled-rope climbing system. Using a pulley to tend your hitch frees you up for one-handed slack-tending. A pulley with multiple anchor holes can also neaten up your climbing system and make it more compact (see the Hitch Climber below) or open up uses for hauling and mechanical advantage. Some climbers like to install a high-efficiency, ball-bearing pulley on the rope bridge of their harness. Using a pulley on the harness bridge reduces wear on the bridge, and lets the climber's tie-in point traverse the bridge more easily. (The Hitch Climber is not to be used in this way.)
Using pulleys throughout your climbing system can help reduce the overall friction present and improve the efficiency of your climbing.
Micro pulleys have lots of uses for tree climbing, one of the best of which is as a slack tender in a split tail climbing system. We have a range of Micro pulleys for you to choose from here, and more 1/2" capacity pulleys available here if you're looking for something else. We also stock the split tails and prusik loops for your climbing system.
The Hitch Climber Pulley has many uses! It can be used for slack-tending and generating mechanical advantage for rescue and gear hauling, not to mention improving work-positioning systems. With three carabiner holes, the Hitch Climber can be the center of many great SRT and DdRT climbing systems. See the Hitch Climber's Guide PDF at WesSpur.com for more ideas. Should only be used with spliced-eye climbing lines.

“It's a little pricey for a micro pulley, but there are good reasons for that. The build quality is top of the line. If you've used other pulleys and thought, "I wish this edge was curved," on the hitch climber, it's curved. If you've thought, "I wish the cut was a little cleaner on this edge," on the hitch climber, it spotless. If you've thought, "You'd think they woulda made the holes a little smaller so my 'biners aren't flopping all over place while I'm trying to climb".....well you get the picture. It can be used 500,000 different ways (or I'm convinced it can be as I seem to imagine up a new one every week). My recommendation: Buy two of them. You'll end up using the second one sooner rather than later and not because the first one wore out either. This pulley is just too handy to only have one on hand (pun intended). ”

“I was weary of the price at first, but after watching Nice-Guy Dave's video demonstration it became obvious to me that the Hitch Climber is the way to go.
“The way your friction hitch and climbing line connect to the pulley allows the tension in your climbing line to straight line the pulley and keep it from flopping all over the place. This makes for a much cleaner and more efficient setup.
“I was also pleased to discover that the Hitch Climber is highly effective at self-tending when foot locking the tail on a DdRT ascent, there is no need to use your hands to advance the friction hitch. Because climbing line tension holds the hitch climber in position the friction hitch gets sucked into the hitch climber all on its own as you advance. The fit and finish are excellent, the pulley runs smooth, the edges are all rounded, and there is very little free play when you open the pulley to install it on your climb line.
“One additional consideration that is not advertised as much as it should be, is that the hitch climber requires a spliced eye climbing line, a large connection knot at the carabiner could interfere with the operation of the friction hitch (a rather dangerous situation). ”
Get your Hitch Climber pulley, carabiners and rope diameter-appropriate hitch cord with a single click. These Hitch Climber sets contain Hitch Climber (red), 2 x DMM Oval double-locking carabiners, and a hitch cord for your rope diameter. Set 1 comes with a 8mm (5/16") sewn Ocean prusik for use on 11mm (7/16") ropes. Set 2 comes with 10mm (3/8") sewn Ocean prusik for use on 12mm (1/2") lines. Set 3 comes with a 9mm sewn RIT prusik which will work on 11mm or 12mm ropes (7/16" or 1/2"), and RockO double-locking carabiners in place of DMM ovals.
The Hitch Climber Rapide replaces the bushing with a bearing sheave for higher efficiency. Both pulleys should only be used with spliced lines, as a knot could interfere with the operation of the friction hitch.

ISC pulley built this pulley to work with the stiff tethers used with the Rope Wrench ZK-2. The wide spacing between the swinging side plates provides plenty of room for various tethers. The Rope Wrench pulley will work with spliced or hand-tied prusik cords.
Rock Exotica's new triple-attachment swivel pulley combines swivel, rigging plate, and pulley into one great tool. The Hydra can be used on your rope bridge for a sliding connection point which also eliminates rope twisting, or even as a lanyard adjuster or to tend your friction hitch (though the swivel won't come into play in that setup). We're sure you'll find many other uses for this great new pulley.
The Hydra can be loaded at any of the three rubber-lined carabiner holes on the swivel top, and has a maximum rope diameter of 1/2” (13mm), breaking strength of 28kN (6294 lb), and a WLL of (5kN 1124 lb).
The SMC Crevasse Rescue (CR) Pulley's diminutive size and featherweight belies its solid strength. Tests to greater strengths than other pulleys in the same range of size and price. Makes an excellent slack-tending pulley for your prusik, which is why you'll find it in our rope climbing kits.
A smooth running 1.20'' nylon sheave runs on a stainless steel rivet axle, and the color-contrasting aluminum side plates rotate for easy rope insertion and removal. Easy to use, easy to carry.
