Technical Details

I acquired my Mad Rock Rescue 8 from Alonzo Guerra in 2012.

The Mad Rock Rescue 8 is forged from aluminum alloy and then soft anodized. Mine is 171 mm. tall, 171 mm. wide, and 16 mm. thick. The rope hole is 65 mm. high and 72 mm. wide. The top center thickness is 13 mm. The shaft length and width are 48 mm. and 41 mm., respectively. The auxiliary hole is 32.1 mm. high and 16.3 mm. wide. The eye measures 37 mm. by 40 mm. The ears are 32.5 mm. long. My Mad Rock Rescue 8 weighs 258 g.

One side of my Mad Rock Rescue 8 is screened with "MAD ROCK," "EXCEEDS NFPA," and "45kN."

Comments

This is one of the following family of essentially identical forged aluminum rescue eights with ears:

Asol, Version B Asol, Version B   Fusion Terminal Rappel 8 Fusion Terminal Rappel 8  
Climb Right Climb Right, Version A   Good Makings, Version A Good Makings, Version A
Climb X Rescue 8 With Ears Climb X Rescue 8 With Ears   Kong Big "8"(805.06) Kong Big "8" (805.06)
Epic Peak Epic Peak   Mad Rock Rescue 8 Mad Rock Rescue 8
Fusion Fusion      

The Climbing Technology Ltd. eight is similar, but the ears are shaped differently. The Climb Right, Version B has a similar design, but it is a milled eight and is significantly smaller. There are several Kong steel eights that also have similar designs, some about the same size as the Kong Big "8" (805.06) in the table, some smaller.

On all of the ones in the table, the eye and ears are larger than they need to be. The belay slot is a reasonable size for a Sticht slot, and insetting part of the slot into the useless portion of the upper rope hole reduces the length of the eight. Still, like all rescue eights, these are too large and heavy for an eight - there are much better devices that are smaller and lighter than these eights but work just as well, if not better.

Technical Details

I acquired my Mad Rock Small Rescue 8 from Mad Rock in 2009.

The Mad Rock Small Rescue 8 is forged from aluminum alloy and then soft anodized. Mine is 109 mm. tall, 80 mm. wide, and 19 mm. thick. This is a bent eight, if it were flat, the thickness would be only 11 mm. The rope hole is 35 mm. high and 53 mm. wide. The top center thickness is 11 mm. The shaft length and width are 35 mm. and  25 mm., respectively. The eye measures 20 mm. by 25 mm. The ears are 13.1 mm. long. My Mad Rock Small Rescue 8 weighs 91 g.

The convex side of the shaft on my Mad Rock Small Rescue 8 is printed with "MAD ROCK" and the concave side has "kN25" in raised forged letters.

Comments

Mad Rock calls this a "Small Rescue 8," but it does not fit my idea of a "rescue 8," whatever that is.

This is one of the following family of essentially identical "mini" size figure eight with ears:

AMP Outdoor 8 AMP Outdoor 8   Good Makings, Version B Good Makings, Version B

These are small eights, and lighter than most figure eights with ears. If these were flat, they would create more friction than most. The bend allows them to be rigged two ways with differing amounts of friction. Even so, the rope hole is shorter than normal, so these eights may provide too much friction on stiff or muddy ropes.

Other small eights have similar bends. Examples are the Chouinard Version B, Faders, Frendo Version B, Kabelwerk Oberspree (perhaps the original design motivating for all of these - and yet not intended to be an eight at all!), and the Trango Penta, but this eight and its equivalents also have ears. Better yet, the ears are placed low where they can function effectively without increasing the size of the eight. For eared eights, I like this design enough to give each example a star.
