How to install E-Z Nail On yourself in just minutes on concrete/tile floors.

Step 1: Slide both doors to one end of the closet. Plum doors with door frame and hold in place. Slide template under doors of front door to out side corner using template and hold in place.

Step 2: Mark floor - throw little O were you will drill 3 holes 2 inch deep.  Use a 5/16 cement drill bit.  (If on concrete floors in apartment floor use a 1/4 in drill bit.  Apartment concrete floors are different then normal concrete floor material and some times you will drill the hole too big. If you are not sure drill a 1/4 in hole first and try the anchor, they should fit tight.  If the hole is to tight then make the hole with the 5/6 drill.)

Step 3: Drive plastic anchor even with the floor into holes and you're done!
