Tensioners 301/302, are tensioners that are manufactured in Mabel Industries, first with the presses we manufacture the aluminum hook, then in an automatic machine we cut the rubber to finally with a press of 10Tn to realize the union of the two components.

The hook in this case is normal, that is, it rotates in the same direction as the closing of the aluminum hook.

Are used for publicity canvases and for tensing small structures that do not have to do much force.
