Determine location of interior framing for installation
of USP’s WS8-HDG or 3/8-in lag screw. Mark that
location on the exterior wall aligned with the deck
joist and the interior wall framing. Note: The band
joist is not an adequate attachment material.
Use tool or blunt object to remove the 2-hole
break-out washer (BO-W) from ADTT-TZ body.
The WS8-HDG screw will utilize the smaller hole
and a 3/8-in lag screw uses the larger hole.
Thread the screw through BO-W and the large
7/16-in hole at the base of the ADTT-TZ. Thread
from the outside of the part. Bend front brace
of ADTT-TZ away from vertical supports at
approximately a 45-degree angle.
With the ADTT-
TZ still attached, use a power driver
to begin driving the screw into the structure at the
location marked in step number 1. Drive screw
horizontally and aligned vertically with the deck joist
into structure approximately 3-in to 4-in allowing
room for installation of the ADTT-TZ in front of the
joist hanger seat (if present). There will be 4-in to
5-in of screw showing at the conclusion of this step.

Align the vertical legs of the
ADTT-TZ in a plumb position with
the two leg anges positioned
on either side of the deck joist
member. At this time, you will
need to bend the front brace at the
proper angle for installation.
With the screw head and washer
tight to the ADTT-TZ, install four
(4) 10d (0.148-in) x 1-1/2-in nails
into top anges (Two (2) on each
side of deck joist). Ensure that
vertical legs and the body of the
ADTT-TZ are kept in a vertical
position during this step.
Bend front brace to proper angle
so it is tight to the bottom side
of the deck joist. Secure front
brace with six (6) 10d (0.148-in) x
1-1/2-in nails.
Re-tighten the WS8-HDG or
3/8-in lag screw as needed to fully
engage with the ADTT-TZ.
