Technical Details

I acquired my Rock House from Thomas Kopp in 2010.

The Rock House is forged from aluminum alloy. Mine is 141 mm. tall, 85 mm. wide, and 15 mm. thick. The rope hole is 49 mm. high and 49 mm. wide. The top center thickness is 12 mm. The shaft length and width are 44 mm. and 25 mm., respectively. The eye measures 26 mm. by 26 mm. My eight weighs 116 g.

One side has "ROCK HOUSE" in raised forged letters, the other side has "KG 3000."

The keeper hole allows attaching a keeper cord that can be connected to the harness to reduce the rik of dropping the eight. A drawback is that the keeper can easily get entangled with the main line. You may think that the keeper holes on these eights are not in a good placebut where else could it be? If it were on the shank or eye, then the keeper would prevent rigging the eight while the keeper was attached to the user. I recommend simply not dropping your descender, but if yuo have a real concern about dropping the eight, perhaps it would be better to switch to a different kind of descender.

The Midi-sized eights have a compact design that causes the rope to make sharper bends, providing more friction on stiff ropes than a standard-size eight. They also weigh less than most eights. The standard-size Rock House provides less friction than the Midi-sized eights. The Fungo has a bend that allows it to be rigged two ways with differing amounts of friction. The C.A.M.P., Version H is a flat Fungo-equivalent that lacks the two friction arrangements.

The Rock House is larger than other such eights in my collection. It's larger keeper tab is distinctive.
