All of the eights in Tables 1 through 3
that have the same finish type are,
for practical rappelling purposes,
interchangeable.

Table 1: Standard, Full Size, Forged Eights

• These are typical eights in size, shape, and material.
• I use a height of 134 to 147 mm. as the criteria for placing a forged eight into this category.
  • Although the CAmnal is slightly larger than this criteria's range, I included it here because of its greater smilarito to these eights than to the large forged aluminum figure eights,.
• Like most eights, all of these are forged from an aluminum alloy.
• In this table, special shading in the ID field background indicates eights that are particularly similar except for markings and possibly finish.

Table 2: Full Size, Forged Eights with Fat Shafts

• These are typical eights in size, shape, and material.
• These eights have fatter shafts so that the rope continually curves around the shaft.
• Like most eights, all of these are forged from an aluminum alloy.
• In this table, special shading in the ID field background indicates eights that are particularly similar except for markings and possibly finish.

Table 3: Full Size, Forged Eights with Flat Shafts

• These are typical eights in size, shape, and material.
• These eights have flattened shafts so that the rope does not rub much on the face of the shaft.
• Like most eights, all of these are forged from an aluminum alloy.
• In this table, special shading in the ID field background indicates eights that are particularly similar except for markings and possibly finish.
