DMM Revolver Screwgate Carabiner — Integrated Pulley Sheave
The DMM Revolver is one of those pieces of hardware that quietly makes your rigging system more efficient every time you use it. The integrated pulley sheave at one end of the carabiner dramatically reduces rope friction compared to a standard carabiner redirect — making it a go-to choice for mechanical advantage systems, speed lines, and hauling setups where friction is the enemy of efficiency. DMM's I-Beam construction keeps weight low without sacrificing strength, and the shrouded nose prevents snagging on webbing and ropes when you're moving fast in the canopy. Screwgate locking for secure, fixed-point connections.

Frequently Asked Questions
What is the pulley sheave on the Revolver used for?
The integrated pulley sheave at one end of the carabiner allows a rope to run through it with significantly less friction than a standard carabiner redirect. This makes the Revolver ideal for mechanical advantage systems (e.g., 3:1 or 5:1 MA), speed lines, and hauling systems where reducing friction improves efficiency and reduces effort.
How does the Revolver differ from a standard carabiner used as a redirect?
A rope running over a standard carabiner spine creates significant friction, reducing the efficiency of any mechanical advantage system. The Revolver's pulley sheave allows the rope to roll rather than slide, dramatically reducing friction and improving the mechanical advantage ratio you actually achieve in practice.
What is DMM I-Beam construction?
I-Beam construction refers to DMM's method of shaping the carabiner spine in an I-beam cross-section, which maximizes strength-to-weight ratio. This allows the Revolver to be carried in multiples on a harness without adding significant weight — useful when building complex rigging systems that require several redirect points.
What does the shrouded nose do?
The shrouded nose covers the gate latch area, preventing it from snagging on webbing, ropes, or other hardware when the carabiner is being moved through a system. This is particularly useful in complex rigging setups where multiple pieces of hardware are in close proximity.
Is the Revolver available with other gate types?
Yes — the DMM Revolver is also available with Quicklock and Locksafe gate options, which offer different locking mechanisms to suit different preferences and applications. See the other Revolver listings for those variants.
