The TileRex is easy to assemble. Just unscrew the two arms from the top of the shoulder block and screw them back into the ends of the shoulder block and it is ready to remove ceiling tiles.
To remove the ceiling tiles just push the TileRex up against the ceiling tile in the ceiling so that it is removed from the grid and angle it so that it will fit through the opening.
To release the tile from the TileRex bring the ceiling tile down to the floor and as soon as the tile is angled over 90 degrees the tile will fall off where you want to stack them.
To store the tool after use just reverse the assembly steps.
The thread in the shoulder block is a standard broom handle thread so if your ceilings are not very high you can buy the head only without the pole.
