ADJUSTABLE LENGTH - This adjustable hanging rope system is better than others like chain or polyester straps. You can adjust the size you want to fit your swings or hammocks, but the daisy chain can only be adjusted in a limited range of length (still for 3.5 inches). STRONG & SAFE - These swing ropes have the same quality and strength as seat belts. Each can hold up to 660 pounds. While the industrial-strength steel makes the buckles nearly indestructible. Safe and fun for the whole family. UNIVERSAL COMPATIBLE - These swing ropes work with almost any pole or tree regardless of indoor or outdoor, such as swing set, outdoor hammock, flying yoga aerial, hanging rope chair, garden swing, seesaw, disc swing, classic tree swing, toddler swing and porch yard swing, indoor swing etc. GOOD QUALITY - Made from commercial grade polyethylene, our swing ropes can survive harsh winters and brutal summers without abrasion. The 3-ply braided design ensures a better, stable and reliable attachment.
