Marker touring bindings. Compatible with Alpine sole, touring sole, and GripWalk boot standards. Compatible sole sizes are from 265-325mm. Release value is 6-16. Brake width is 110mm. I no longer use these as I switched to tech bindings. Screws are also included. Compared to tech bindings, these are heavier, but the rigidity when skiing is quite high, making for a smooth ride. There are scratches from use, but there are no functional issues or problems when using them. Please note that the mounting instructions are not included. Thank you.
