DMM Ultra O Carabiner Grey
- Product Review (submitted on February 14, 2015):
- This biner is the most true oval I've seen and it's very smooth and rugged. The i-beam construction adds strength and the color choices are appealing for easily identifying them should they land in sawdust or grass ect. I will say the gate is slightly harder to open than the rock excotia rock o biner, which has a pull down as opposed to DMM's pull up and twist at a 45 degree. If your looking for Biners to use with a hitchclimber setup these are the Cadillacs!
