Brand new skateboard slide rails/ribs made by Creature.
They are low profile but still quite wide so have some material to "slide" through before they are done. Nice and light weight for modern boards. Best of all though they have a cool "serrated" bat wing style edge. Mount them so that side is to the middle of your deck for better grabbing.
These ones come with 10 "phillips headed" self-tapping screws, so you don't have to drill your plank...far easier and lighter.
