Door Installation Guide
Step 1:
Gather your tools and
materials! You will need:
 Tape measure
 Hammer
 Carpenter square
 2 ft. and 6 ft. long levels
 Wooden shims
 Power Drill
 #12 x 3 in. exterior
grade screws
 Safety glasses
 Caulking gun
 Clear exterior sealant
 T-10, T-15, and T-25
drill bits
 2.5 mm Allen key (aka
Allen wrench or hex
key)
 A helper to assist in
holding the door
Step 2:
Make sure that the door will properly fit
in your opening. The recommended
rough opening is ½ in. wider and ½ in.
higher than the door unit. Ensure the
floor is level and use a carpenter’s
square and level to check that the
opening is square and plumb. Apply
beads of caulk to the underside of the
door sill. Place the frame into the
opening and shim into place behind the
installation holes. Use a level to ensure
the frame is plumb, level, and square.
Step 3:
Anchor the frame with #12 x 3in. screws
using the pre-drilled installation holes at
the top and bottom corners. Be careful
not to over tighten or strip the screws,
and recheck for plumb, level, and square
when finished. Shim and anchor the
frame through the remaining pre-drilled
installation holes, taking care not to bow
the frames when shimming.
Step 5:
After completely anchoring the frame,
position the door panel in place. Two
people are recommended for this step
as well as a wooden block under the
door to hold the door at the correct
height to line up at the hinges.
