The BiWire is a totally new type of wire gate carabiner. This patent pending design features an outer gate in addition to the normal inner gate. The outer gate protects the inner gate and prevents the rope, or other objects, from opening it.

Use the BiWire as an alternative to a non-locking carabiner when you want extra security. It is perfect to use when you are clipping your lead rope and you want to prevent the rope from running over the gate and opening it, as can happen with conventional non-lockers.

If you have an opposable thumb, the BiWire is easy to open one-handed with a little practice. And it comes off whatever it’s clipped to as easily as a non-locker – just open the inner gate and pull it off as you would a non-locker. It is obviously very resistant to dirt and ice.

The BiWire design is inherently very strong – check out the 30kN closed gate strength, which is significantly stronger than a conventional gate. The outer wire gate is also much stronger than a conventional locking sleeve against an inward force. Normal biners are only usually only 2-3kN in this regard, but the BiWire is much stronger at over 7kN.

The extra security of the BiWire adds very little weight, only the weight of an extra wire gate, at about 4 gm.

The BiWire should not be used to replace a regular locker, because the inner gate is not physically secured by a sleeve as it is in conventional locking carabiners. It could be possible for something to open the inner gate and then it could come unclipped. So use it as an alternative to a non-locker when you want extra strength and security.

The BiWire will eventually be available in several sizes. This first model, the rockD, is a general purpose “D” shaped frame and it might be the strongest biner on your rack.

Rock Exotica Omni-Aztec Elite ®

RRP $395.00 incl gst

The Rock Exotica ™ Omni-Aztek Elite® system was developed in Arizona through ‘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 prussik can be attached at either end (orange to orange, or blue to blue). The progress capture prussiks are laced onto the restraint cord and then formed into a directional prussik hitch (3 on 2), which prevents the inadvertent loss of the prussik once assembled. One quick pin is sold with each set of blocks. Additional pins may be purchased if needed.

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 (36 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” (38mm) and accepts up to ½” (12mm) rope.
