  • Publication number: 20160069368
    Abstract: A rapid mounting hallow wall anchor comprises a cleat with latching tooth and hanging flange, and a T-shaped anchor structure with latching cogs on its stem. The cleat comprises a tube with a flange near or at one end of the tube. There are latching teeth inside of the tube for engaging the latching cogs on the stem. The tube flange can be made to have a groove or hook on where objects can be hung. A cross bar joins one end of the stem with a cross bar hinge. The cross bar hinge allows the cross bar to be bended for insertion into a drilled hole in a plasterboard of a hallow wall.
