Slacklining requires two stable points between which you can rig up the slackline. These could be trees in the park, pillars in the city or boulders in the mountains. You can buy slacklines - a 25-50 mm-wide band - with different elasticities for different slacklining goals. The ratches attach the line to the fixed objects. In most slackline sets, you'll usually find the slackline with a ratchet and tree protection. High-quality sets also include round slings and shackles. Sets for rigging up the slackline in the garden also come with a frame, nails and ground plates.
