The Revolver from DMM is an innovation in carabiner design, not only does it use 'I' Beam construction which makes it incredibly strong and light it has a roller built in, this roller reduces friction and when used on placements where rope drag is expected it makes a big difference. The roller also reduces wear and tear in fall situations as well.

The Revolver was the reason for I-Beam technology being concieved because this process crucially allows the body to deal with the stresses involved in placing a pulley into a carabiner whist remaining light enough for general use.

Technical details:

• The 7075 series pulley runs on a dry lube "IGUS" bearing, which is seated on a high tensile stainless sleeve and spindle. This will continue to rotate with loads up to 11Kn before any deformation occurs.In the unlikely event that the pulley does deform - and we have not seen one case yet - the biner still acts as a full strength (24Kn) carabiner.
• It has been anodised for protection against the elements especially coastal and rigourous mountain enviroments.
• Lubrication:The 'IGUS' bearing will run without lubrication, however like all gates and barrels a periodic clean and oil will prolong the units life.
