Swivel double pulley for pulling two ropes simultaneously. The swivel function aligns the pulling direction and the ropes, making it suitable for use with high anchor points and tripods. It minimizes the overall length, maximizes the pulling stroke, and the pivot plates on both sides allow for quick rope attachment and detachment. Purchased about 5 years ago. There are no problems with the performance, but please understand that I cannot take responsibility for any issues arising from its use. The condition is good, but as it is a used item, please refrain from claims and returns.
