DIRECTIONS FOR ASSEMBLY OF THE OMNI–AZTEK ELITE® “SET-OF-FOURS”

(System End)

Congratulations on your purchase of the Rock Exotica Omni-AZTEK Elite® pulleys! The AZTEK system was developed in Arizona-based

Ropes That Rescue Ltd®. rigging programs around the world. These, configured as a “set-of-fours” (double-blocks) as shown in detail in

these instructions, will enable the rescue practitioner greater versatility in a personal mechanical advantage (PMA) for rescue and general

rigging. These 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# (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# (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 prusik once assembled. One quick pin is sold with

each set of blocks. Additional ones may be purchased if needed or if one wished to hold a spare in the opposite block. NOTE: These

directions are available IN COLOR in pdf form from www.ropesthatrescue.com/aztek.htm

INSPECTION: Blocks should be inspected before and after use to insure that connecting hardware is intact. All software should be

inspected for wear and glazing. These should be replaced as this occurs before use. Replacement software is available.

1. To begin the assembly of your Rock Exotica Omni AZTEK Elite® “Set-Of-Fours” find a large flat surface to lay the components out. You should have

components as follows:

•1 ea. Rock Exotica Omni AZTEK Elite® blue pulley

•1 ea. Rock Exotica Omni AZTEK Elite® orange pulley with

•Separate becket cover plate (shown attached to the orange pulley below)

•Quick pin (shown attached to the blue pulley below)

•1 ea. STERLING 8mm or 9mm AZTEK accessory cord with sewn eye on one end only (recommended length 15.25m or 50 ft.) 1

•1 ea. STERLING AZTEK orange ratchet

•1 ea. STERLING AZTEK blue ratchet

2. Remove pulley becket cover from orange pulley by removing small screw

and lock washer (if attached)

3. Slip end of sewn eye on accessory cord over becket (Note: this may

take some force)

1Personal AZTEK Elite® cords should be one color and the color changed to a different color for kits used in other locations (like at the foot end of the litter)

4. Reinstall becket cover plate with screw and lock washer then tighten

with screw driver. Inspect this screw often for tightness. Do not use if this

cover plate is loose.

5. Arrange your two Rock Exotica Omni AZTEK Elite® pulleys on the

ground as shown. The orange pulley should be laying with the sheaves

parallel to the ground and the blue sheaves should be perpendicular.

6. Pull balance of accessory cord through blue pulley sheave as shown

(top to bottom—blue pulley becket is on opposite side)

7. Reeve orange pulley with cord clockwise as shown. Be careful to reeve

exactly as shown in the photos.

8. After threading the bottom sheave on the orange pulley, put loop of blue

ratchet onto cord as shown before threading the next sheave on the blue

pulley from bottom to top

9. After threading the second sheave on the blue pulley, put loop of

orange ratchet onto cord as shown before threading the next sheave on

the orange pulley as shown (counterclockwise)

NOTE: Make certain that the loop formed at the top of each ratchet prusik next to the shrink tubing is just small enough to fit into the quick pin receptacle

on either pulley. This may be done by slipping the cord sewn into the loop through the shrink tubing installed at STERLING ROPE

small quick pin which comes with AZTEK Elite® pulleys

14. Pin in place orange ratchet to orange pulley or blue ratchet to blue pulley. DO NOT attached orange ratchet to blue pulley or vice versa. Only one
