How to Install a TV on hollow wall when you cant find the studs
Installing a LED TV with SNAPTOGGLE® Toggle Bolts from TOGGLER® holds your TV securely on all walls (including drywall) so that it does not come loose or pull out.
In hollow walls (walls with a cavity behind or in them, like drywall, plaster on lath, or concrete block) use SNAPTOGGLE® Toggle Bolt.
To install flat screen TV’s and TV mounts using the SNAPTOGGLE Toggle Bolt:
Follow the instructions included with your flat screen TV or TV mount for marking the location of each anchor in the wall. If possible Try to locate at least one, if not two, of the anchors into a metal stud.
At each location, drill 1/2″ diameter hole. Hold metal channel flat alongside plastic straps with top of channel facing up and slide channel through hole.NOTE: Minimum clearance behind wall: 1-7/8″.
Hold ends of straps between thumb and forefinger and pull toward you until channel rests flush behind wall. Slide plastic cap along straps with other hand until flange of cap is flush with wall.
Snap straps at wall by pushing side to side, snapping off straps level with flange of cap. Repeat at each location.
Place TV mount over flange. Insert screw through bracket and tighten until flush against bracket, then stop. Repeat for each hole in TV mount bracket.
Following the manufacturer’s instructions, install TV mount in bracket.
