ADJUSTABLE LENGTH - This adjustable hanging rope system offers more flexibility than others like chain or polyester webbing. You can adjust the size to fit your swings or hammocks, unlike daisy chains which have a limited adjustment range (typically around 3.5 inches). STRONG & SAFE - These swing ropes offer the same quality and strength as seat belts. Each rope can hold up to 660lbs. Industrial strength steel ensures the buckles are highly durable. Safe and fun for the whole family. UNIVERSAL COMPATIBLE - These swing ropes are compatible with nearly any pole or tree, both indoors and outdoors. They work with a variety of applications such as swings, outdoor hammocks, flying yoga aerials, hanging rope chairs, garden swings, seesaws, disc swings, classic tree swings, toddler swings, porch yard swings, and indoor swings. GOOD QUALITY - Made of commercial grade polyethylene, these swing ropes resist damage from harsh winters and intense summers. The 3-braided design provides strong and reliable support.
