The Hemp Climbing Ropes are 1-1/2" in diameter ropes containing 12% to 18% mineral oil lubricant for long life. They are securely attached with a heavy-duty steel fitting for years of durability.
If you ordered a rope with rubber knots, the knots are anchored every 12".
The Soft Dacron Ropes are ideal for elementary physical education programs. No-twist spun dacron material is easier on the hands than hemp ropes and will wear better than cotton.
Dacron ropes are Hypoallergenic which will not cause the allergic reactions that are possible with treated ropes.
Collegiate ropes are finished with a vinyl boot.
