For 1 3/8" Thick Hollow Core Bi-Fold Doors
If you have chosen to use a "Dummy Lever Knob" or similar application where more than one bolt is required to fasten the knob/lever, see examples below.
The installation process will require; 1) Locate and mark the 2 or 3 bolt hole locations on the front panel, 2) Using a 11/64" drill bit, drill a hole through both front and back door panels at each bolt location, 3) Follow steps 2, 3 & 4 above to open the hole up in the back panel and to insert the Knob Secure spacer, 4) If using a dummy lever knob use through bolts (Flat Head 8x32, 1 1/2" or 1 3/4"), inserting them from the front to the back and installing a metal washer and nut on the back side of the door, 5) If necessary, cut off the excess bolt length with a hacksaw and file the end of the bolt smooth.
