Table 9: T-side Figure Eights

• These eights have ears on the side. Their primary purpose is to provide a convenient place for tying the rope to lock off.
• The AustriAlpin Guide, Hugh Banner, Mizo, and some of the Krok and Chinese eights are similar, with each having T-horns on each side.
• In this table, special shading in the ID field background indicates eights that are particularly similar except for markings and possibly finish. A pale orange background in the Device column indicates a double-T-sided eight.
