The FlipToggle® anchor’s strong toggling mechanism supplies extra holding power in drywall, plaster or hollow concrete blocks. Its main feature is its ability to be installed in thicker hollow wall material, up to three inches thick. Its simple and effective tilting mechanism ensures a trouble-free installation every time, and is twice as strong as the regular toggle bolt of the same bolt diameter. The Fliptoggle® requires a 1/2 hole regardless of its diameter, and can be used with any bolt length. Available in diameters of 1/4 and 3/16.
