Installation:
• Use all specified fasteners.See Product Notes, page 10.
• Install with USP’s THR 1/2" threaded rod or equivalent.
• Position DTB-TZ on deck joist in a location where the 1/2"
threaded rod or bolt may be threaded through the bolt hole.
• Drive WS15-GC wood screws into joist.
• Re-install threaded rod or anchor bolt. Secure with washer
and nut.
• Tighten anchor bolt nuts finger tight snug to base plus 1⁄3

in place.
