New Metolius Offset TCU’s are designed specifically for hard to protect flared micro-fissures & pin scars. They use two smaller cam lobes and one larger lobe to accomplish this.  Working with Ivo Ninov and partners over the past two years has convinced us of their validity.  Ivo has raved about their performance on free & aid walls in Yosemite and Zion and is quoted as saying “you guys must do these units…they are sooooo bomber”!  The narrow head width fits nearly anywhere and the U-shaped body absolutely doesn’t hinder placement.  In fact it gives a very stable framework in which to hold the cam lobes.  Unlike other brands, the Metolius TCU’s can withstand multiple walls worth of abuse.
