Cam faceTechnical Details

Kevin M. Mai ZhongJie helped me acquire this #654 flipline adjuster from I Climb in 2023.

My I Climb #654 is 89 mm. long, 72 mm. wide, 36 mm. high, and weighs 226 g.

The #654 consists of a frame, spring-loaded cam, and hex cap screw axle. The frame and cam are forged aluminum. The cam face has six rounded horizontal teeth.

The front is printed with "⇑" over "UP," "CE 0120," "EN358:2018," "kn 15," and "Ø12 mm." The other side is printed with "⇑" over "UP," "iclimb®," and "Made in Taiwan."

My Antec Pole Lanyard Maxiglisse came as part of a flipline. It was designed for climbing tree and utility poles. The others were sold as rope grabs. I was never comfortable calling these rope grabs. Skylotec's web site sells the Ergogrip as part of a work positioning lanyard (i.e., a flipline in my terminology). The I Climb #654 was certified to EN358:2018, indicating that it was also for work positioning (i.e., for a flipline). The NTR has EN341 markings, but this standard is for descenders (making no sense to me). I think that the NTR would also function better in the flipline role. For these reasons, I'm calling all of these flipline adjusters rather than rope grabs.

The three large finger grooves and the thumb tab on the spring-loaded cam make these easy to operate as flipline adjusters. They each feel good in my hands.

In each of these, the adjustable clamp resembles an ascender in some ways. The cam pivots on the others are fixed, so none of these can be attached to or removed from the rope except at the end of the rope.

The I Climb #654 has a toothed cam surface, while the other three have smooth cam surfaces.

This NTR was sold as a Rope Grab, but I have some doubts about this. The Antec Pole Lanyard Maxiglisse has a very similar device used as a NTR adjuster, and I think that the NTR would function better in that role, so that is how I am classifying it.

The Skylotec Ergogrip is similar, but the NTR uses a hex cap screw for the anvil, while the Ergogrip uses a rivet. This makes it easier (but not easy) to put the NTR on rope when the rope ends are not available.
