TERRASTILE DOOR INSTALLATION INSTRUCTIONS
3. Determine the high point of the masonry sill using string line or transit and shim the balance
of the opening to match. Shims/blocking at the sill need to provide support to the threshold
and the bottom ends of the jambs, particularly on the hinge side. The door leaf’s full weight
is carried through the butt hinges into the jamb and the jamb into the sill. This is why it is
very important to shim/block solid the bottom of the hinged jamb to the opening. (Do not
anchor the sill at this time.)
4. After completing step 3 which will level the sill and support the weight of the door, shim and
anchor the hinged jamb. Shim behind all hinge points (and snubber) to plumb the hinged
jamb and center in the opening. Some shimming at the top and bottom of the locking jamb
may be necessary at this point to provide pressure to hold the hinge jamb shims in place.
Support the weight of the door leaf to prevent twisting of the frame and open the door leaf to
install the perimeter hinge anchors as shown in Fig D.

The sill and bottom of both jambs need
to be supported with shims/blocking.

Warning !
Do not snap the threshold
cover on until the door is
completely anchored. Check
for final fit and make sure
anchors are sealed.

Due to varying opening conditions, construction substrates, door configurations, and
design pressures, the door shim or blocking methods can vary greatly. A fully installed
door must be plumb, level, and without rack or twist to operate properly. One point of
reference to a proper fit is a nominal 1/8” or equal gap between the frame and operable
door leaf (see Fig. C).

It is important not to block the
flow of water over the anchor
heads when sealing the anchor
heads. (See note 8, pg. 7 of 13)
