Technical Details

I acquired my NTR from Kangjin Liao in 2017.

My NTR is 98 mm. long, 75 mm. wide, 35 mm. high, and weighs 230 g.

The NTR consists of a frame, spring-loaded cam, and hex cap screw axle. The frame and cam are milled aluminum. The finger grooves are comfortable and the shape of the upper cam makes it easy to operate the cam with the thumb.

One side is etched with "NTR." The other side is etched with an up-pointing arrow, "UP," "Ø 9-12mm," "CE1019," "EN341," and "use correct rope only."


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 flipline adjuster, and I think that the Ergogrip 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.
