Climbing Gear - DMM Revolver Screwgate
The Revolver Screwgate is a locking biner with an Integrated pulley, which means dramatically reduced friction in any system using these biners. Perfect for rescue and hauling.
Following their success with the Revolver Wiregate, DMM have tweaked their original design and have added a locking gate. This makes the pulley/biner combo fully certified for use as as karabiner and pulley, perfect where complete safety and legislative compliance is a requirement. The Revolver also offers you options in terms of rigging hauling systems or improvising rescues making this carabiner a very versatile piece of kit.
The keylock nose means that ropes and gear don't snag or catch with the gate open.
In the Revolver karabiners, I-Beam technology is used, reducing weight and maintaining overall strength. This allows the innovative Revolver design to deal with the stresses involved in placing a pulley into a carabiner whist remaining light enough for general use
DMM REVOLVER SCREWGATE FEATURES
-
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 rigouirous 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.
-
Unique pulley wheel design locking biner
-
Strong and lightweight I-Beam construction
-
Shrouded nose to reduce snagging
