This Slackline kit is great for all ages! * This kit has a anchor system to reduce stress on the main walking line also allowing it to lay perfectly flat unlike other loop systems you might find out their. * This kit will last a lot longer than loop set-ups because the anchor system is separate from main line also allowing you to replace just the main line or just an anchor. * By having anchors on either side it gives you a true 50ft set-up * This kit is Hand Made In USA !
