Oval carabiner for off-loading and add-loading via tubing loops and webbing chains (daisy chains).
Aluminum with non-locking gate.
These are less expensive if purchased through other online sources, but if you don't want to go looking, here they are.
NOTE: Precise use of all RTS Exercise Tools is not as obvious as it may seem. They are not recommended for use by trainers that have not attended RTS courses that include detailed execution, progression, and cuing of/on the specific device!
In fact, if you think use of any of these tools can be generalized or standardized without considering the idiosyncratic realities of each and every individual then you obviously don’t understand it’s purpose nor the forces and internal influences associated, so please do not purchase from RTS.
