Recognition of the unique requirements found in Swift Water Rescue, we've created an entirely new pulley for 2005.
This aluminum pulley weights 6 oz. and features a 2'' sheave. The anodized aluminum sideplates feature a series of holes that help to minimize the hydroplaning effect that might otherwise occur with a typical pulley. Sideplates are also configured to allow this pulley to work as a Prusik Minding Pulley. Sealed Ball Bearings provide optimal efficiency. One sideplate is red and the other is black.
Weight: 6 oz. (170g)

T.R. Pulley [SM159500]
1 1/4", Oilite Pulley
$29.40
Despite its diminutive size the TR Pulley can handle full-sized work loads and is ideally suited for use with the very popular SMC Aluminum Locking D Carabiner. While most people will use the TR Pulley with lightweight aluminum carabiners the TR Pulley can be paired up with a rescue carabiner as large as the SMC Large Steel Locking Carabiner. The bell-shaped top hole allows the carabiner to be rotated freely and completely. A durable aluminum sheave is paired with a true Oilite Bearing on a zinc-coated axle for reliable performance at a reasonable cost. Oilite Bearings are self-lubricating and highly wear and corrosion resistant. Hallmarks of SMC pulley design are the color contrasting aluminum side plates that rotate for easy rope insertion and removal. The MBS and lot number for each pulley is permanently laser-etched into the side plate. Intended for use with rope up to a maximum size of 1/2”. This pulley is not suitable for use in a tyrolean traverse. One sideplate is green and the other is grey.
Accepts ropes up to 1/2"

On Sale!
Designed for passing knots in rope.
The new Kooteny HX from SMC is the most advanced Knot Passing Pulley on the market. This is an entirely new and more compact design and lives up to its "HX" (High Performance) name as the lightest, strongest, most efficient and durable high strength alumimum sheave. Sealed ball bearings provide optimal efficiency multiple component systems. The primary carabiner hole accepts numerous rescue carabiners. Secondard carabiner holes are provided for use with tag or belay lines. Two quick-release pins may be used in order "lock off" the sheave when a high strength tie-off is required. Adding to its versatility, the Kootney HS may also serve as an edge roller for rope protection.

On Sale!
Trolley Brake Block A perfect companion to our Trolley. Carved from dense Appalachian hardwood and sealed with an environmentally safe preservative. The striking surface is crafted from ultra-high molecular weight polyethylene, noted for it's exceptional wear resistance. Steel hardware and a galvanized eye bolt round out the package.
User Directions:
The brake block is constructed of 2 pieces of hardwood bolted together with a yellow striking surface. You unbolt the blocks, put your cable through the middle and re-secure the blocks. You need to have 2 pieces of industrial shock cord of equal lengths, which you attach to the eye bolt. These are what you use to anchor the brake block, whether it be to a building, the ground, etc. The brake block must be set at least 20-30' from the end of the zip line. Once the brake block is secure, the trolley would slide down the cable and srike the yellow surface which would essentially stop it.
Length: 23cm.

The Rock Exotica™ OMNI BLOCK® is a mix of the old and the new. Rotating swivel pulleys, called “blocks” in year past, have been around for centuries with drawing dating back to ancient Greek inventor, Archimedes (The first know recorded source of the common pulley system). Originally the first such pulleys were carved and fashioned from actual blocks of wood reinforced with metal banding to prevent the wood from splitting under load. Up to now, rescue pulleys have been the standard side swing plate models that involve rotating the side plate and the introduction of the rope into the sheave. Increased strength is cited as the main reason that life safety pulleys are designed this way.
Incredibly quick to attach, the Rock Exotica Omni Block is a high strength (38 kN), swiveling rope block/pulley. Like RE’s popular swivel connector, these pulleys eliminate twisting from rope rigging systems with smooth, ball bearing action. Each precision fabricated alloy block has a unique button-activated release feature that allows instant access to the sheave for midline attachment. The milled alloy attachment eye is large enough to accept most carabiners and snaps. Pulley 1.5” and accepts up to ½” rope.

Aztek Pulley (1 Pulley)
, Red or Black [PL-AZT]
$84.19
$79.99
On Sale!
The Aztek system was developed in Arizona based Ropes that Rescue Ltd rigging programs around the world. These, configured as "set-of-fours" (double blocks) will enable the rescue practitioner greater versatility in a personal mechanical advantage (PMA) for rescue and general rigging. The swivel Omni pulleys (blocks) are hewn from a solid block of high strength aluminum and are engineered with great pride to withstand over 8,000 lbs (36kN) of tensile force end to end. Sterling Rope Company has also designed sewn products for these pulleys including the 8mm restraint cord, rated at 4,270 lbs (19kN) and both ratchets in two colors, and shock absorber/restraint cords.
The set of two blocks are different colors for ease of identification. Turn the set-of-fours one way and you have a 5:1 mechanical advantage. Turn it around and a 4:1 w/change of direction is the result, making this PMA extremely versatile.
Also, the progress capture ratchet prusik can be attached at either end (orange to orange, or blue to blue). The progress capture prusiks are laced onto the restraint cord and then formed into a directional prusik hitch (3 on 2), which prevents the inadvertent loss of the prusic once assembled. One quick pin is sold with each set of blocks. Additional pins may be purchased if needed or if one wished to hold a spare in the opposite block.
NOTE: Generally, 2 Aztec Pulleys would be used together with 1 Rope Cover and 1 Quick Release Pin 1/4"
