This Steel Debris Grabber is made of light weight steel so it is light and strong. Each size is telescopic and features a rope that is attached to the movable, leveraged prongs on one side. As the rope is pulled up and out of the manhole the debris is caught against the permanently curved prongs on the other side. The leverage generated holds it tightly as it is pulled up. The tubing handle has three sliding lockable sections that are adjustable to any size you want to the maximum of either 4.5M (15’), 6.4M (21’) or 7.3M (24’). They come with a nylon rope that is attached to the tool at both ends.
