Installing Joist Brackets
Pre-Installation
INSPECTING JOIST SPACING
MOST DECKS ARE CONSTRUCTED WITH JOISTS SPACED 12” or 16 “ ON CENTER. IF JOIST SPACING EXCEEDS 16” ON CENTER, 1”x3” PRESSURE TREATED WOOD FURRING STRIPS WILL NEED TO BE INSTALLED TO UNDERSIDE OF JOISTS SO THAT DRYSNAP BRACKETS CAN BE SECURED EVERY 16”. THIS REFERS TO JOIST SUPPORT ONLY, SEE INSTRUCTIONS FOR PROPER POSITIONING OF JOIST BRACKETS.
CHECKING THE JOISTS
PRIOR TO ANY INSTALLATION, IT IS IMPERATIVE THAT THE INSTALLER INSPECTS THE UNDERSIDE OF THE JOISTS IN SEVERAL LOCATIONS. IF THERE ARE ANY JOISTS THAT ARE WARPED OR IRREGULAR, AND/OR IF THE JOISTS ARE NOT LEVEL OR POSITIVELY SLOPED IN THE DIRECTION OF INTENDED WATER FLOW, THEY WILL NEED TO BE CORRECTED PRIOR TO PROCEEDING WITH INSTRUCTIONS. MINOR IRREGULARITIES MAY BE CORRECTED BY ADDING SHIMS OF THE APPROPRIATE THICKNESS. IN SOME INSTANCES, FURRING STRIPS OR ANGLED RIPPED WOOD MAY NEED TO BE INSTALLED TO CORRECT THE OVERALL SLOPE BEFORE INSTALLING THE DRYSNAP SYSTEM. FAILURE TO ADDRESS THIS WILL LIKELY CAUSE PERFORMANCE ISSUES NOT RELATED TO THE PRODUCT, AND WILL SUBSEQUENTLY VOID THE PRODUCT WARRANTY.

1 Make sure your ledger board (main support board attached to house) is properly secured and flashed. There should be a minimum of 8” of flashing out from ledger board (FIG.1-A) . If flashing does not extend past the gap between the first two deck boards, install gutter along ledger board after DrySnap system is installed.

2 Mark your chalk line nearest the ledger board. Measure 3-1/2” out from the ledger board on opposite sides of deck, and pop or snap chalk line (FIG.1-B). This mark will be your “center” mark for positioning the joist brackets.

3 Mark your outermost chalk line. Measure 3-1/2” out from the beam on opposite sides of deck and pop or snap chalk line (FIG.1-C). This mark will be your “center” mark for positioning the joist brackets.

4 Proceed to snap the middle chalk lines. Beginning with the ledger board side, measure, mark & snap chalk lines every 20” apart (FIG.1-D). Again, this mark will be your “center” mark for positioning the joist brackets. Spacing between rows should not exceed 20”, including the last row.

5 Before installing joist brackets, place a level on the joist in several locations to make sure deck is level or pitched toward drainage direction of system. (Inconsistent or bowed joist are covered later in these instructions.)
6
Install first joist bracket by aligning the center of the joist brackets with your chalk line. Start in middle of first joist by fastening bracket with male keystone snap closest to outer perimeter joist. Make sure center of bracket is lined up with chalk line.(FIG.2-A)
Use 2 1/2” screws for rows 1-5, and 3” screws used on rows 6-8.(FIG.2-B)
