DMM Revolver Locksafe Pulley Carabiner
The DMM Revolver Locksafe combines a high-strength aluminium carabiner with an integrated pulley wheel, providing a compact and lightweight solution for professional rope rescue, hauling systems and rope access applications.
The integrated pulley wheel reduces friction when rope is redirected through the carabiner and can be used to create lightweight mechanical advantage systems. This makes the Revolver particularly useful where space and equipment weight are important considerations, including swiftwater rescue, technical rope rescue, rope access and working-at-height applications.
The Locksafe automatic locking gate requires three distinct actions to open, helping prevent accidental opening while the connector is in use.
Key Features
- Integrated pulley wheel reduces friction and improves rope-running efficiency
- Compact alternative to carrying a separate small pulley and carabiner
- Locksafe automatic locking gate requires three separate actions to open
- Keylock nose eliminates the traditional carabiner notch, reducing snagging on ropes, slings and equipment
- Lightweight I-Beam construction provides an excellent strength-to-weight ratio
- Pulley wheel is functional with loads up to 11 kN
- Particularly useful for hauling systems, rope rescue, counterweight systems and rope redirection
- Suitable for professional rescue, rope access and working-at-height applications
Integrated Pulley Wheel
The Revolver's integrated pulley wheel allows rope to run more efficiently than it would through a conventional carabiner. It can be used at rope redirects to reduce friction and rope drag, or as part of a lightweight hauling system.
With the pulley wheel functional with loads up to 11 kN, the Revolver can provide a compact way to add mechanical advantage without carrying a separate pulley.
Locksafe Automatic Gate
The Locksafe gate is an automatic locking system requiring three distinct actions to open. Once released, the gate automatically returns to the locked position.
This provides an additional level of security for professional applications where maintaining a secure connection is critical.

Professional Rescue Applications
The DMM Revolver Locksafe is a useful addition to a professional rescue kit where compact equipment and efficient rope systems are important.
Its integrated pulley can be particularly useful for:
- Swiftwater and flood rescue hauling systems
- Technical rope rescue
- Rope access
- Mechanical advantage systems
- Rope redirection
- Counterweight systems
- Equipment hauling
- Ascender-based hauling systems
Note: The Revolver's integrated pulley wheel is not a substitute for a dedicated rescue pulley where the application requires the specifications or performance of a purpose-designed pulley. Always use the product within its manufacturer's specified limitations and in accordance with the DMM instructions for use.
