STEP 3
Drill holes.
Prepare your power drill with a ⅜inch (10mm) drill bit.
Align the drill bit over your mark and hold the door
steady. Keep the drill level and straight.
Drill halfway through on the first side. Then drill the
remaining half from the other side of the door. This
prevents blowback damage to the door and improves
accuracy.

Since the 2⅛inch (54mm) boring hole already exists in this example,
the lower support bolt will go through the boring hole. Only the
upper 10mm hole will need to be drilled. If your door is prepped with
a smaller boring hole, use the template to drill the additional lower
3/8 inch support.
