Not only holds a lot of weight but can be reused. Fits most anchors The assembly of the bolt consists in passing the lever through two large holes: the first in the part to be fastened and the second in the surface to which it will be fastened.For toggle switches, the toggle switch only needs to be passed through the second hole, as it is permanent attached to the mounting surface with a plastic sleeve. This design only allows the bolt, not the cylinder, through the first hole. This also allows the user to replace the bolts that come with the product with other types of screws on their grips, etc. Unfortunately I couldn't hang the hammock on the walls of my bedroom where eyebolts screwed into wall studs work better and would.
