Pulley on two axles Petzl Reeve Double 

Petzl Tandem® Speed is a high performance double block for use in lifelines and zip lines.
Combining two pulleys and a rigging plate, it is an integrated solution designed to simplify the installation of tensioned rope rescue systems.
The compact design limits the number of connectors and the height of the system.
Operations and efficiency are optimised:
- Triple opening of the movable side plates, possible even with gloves;
- Red indicators provide a visual warning when the side plates are not properly locked.
- Two large-diameter pulleys mounted on sealed ball bearings provide excellent efficiency
- Possibility to configure the system before installation on the main line
 Various configurations and connections are possible:
- The system can be made redundant by placing two REEVE pulleys side by side (if the rope spacing allows), or by connecting the pulley to the upper rope connection at a greater distance
- The pulley can be used in traction systems
- Hole design allows threading for direct connection of ropes or slings
- 19 mm holes allow for the passage of most carabiner bushings
- Uneven number of mounting holes allows the system to be centred and balanced
- Up to three people can be connected at the same time
