The DMM Ultra O Screwgate is an extremely symmetrical oval climbing carabiner, ideal for use with assisted belay devices, pulleys, swivels and shackles. 

Some oval carabiners are not as symmetrical as others, making them less useful for their designed purpose. The DMM Ultra O is one of the most oval shaped biners available and performs particularly well in a 'big wall' environment, and any other situations where the carabiner needs to allow the attachment points to be centralised and hang straight. 

Features

  • Oval shaped locking biner for rigging stability and central positioning of attachments
  • Ideal for pulley systems and aid climbing
  • Strong and lightweight I-Beam construction
  • Keylock nose to help prevent snagging
  • Generous rope radius

Specification

  • Gate Clearance mm: 22
  • Gate Closed kN: 25

  • Keylock: No
  • Minor Axis kN: 12
  • Width Widest mm: 66
  • Length: 109mm

  • Weight: 67g

rounded out!

perfect for the ascender as its equal shape on each end preventing it from getting caught in the ascender as other biners get stuck and caught in the top hole. perfect combo
