Edelrid Spoc

"The ultra-light pulley with backstop is an indispensable tool for anyone working in demanding environments. Thanks to the option of fixing the backstop in the open position, the device can also be used flexibly as a simple pulley. The ball-bearing mounted aluminum roller with a diameter of 20 mm ensures an impressive efficiency of 92 %, which guarantees efficiency and reliability at work"
"Particularly noteworthy is the clamping cam, which ensures optimum grip even with icy or dirty ropes. This makes the pulley ideal for use in crevasse rescue, when lifting heavy loads or as an emergency rope clamp. Compatibility with ropes from 7.0 to 11.0 mm in diameter, including the EDELRID RAP LINE, offers a wide range of applications and flexibility."
"With this pulley from Edelrid, you have a robust and functional piece of equipment at hand that has been specially developed for extreme conditions and remains light in weight."
