DTB Deck Tie Back
The DTB-TZ Deck Tie Back provides positive anchorage between the
deck framing and the exterior wall with a load carrying capacity that
exceeds building code requirements. When used in conjunction with
MiTek’s triple-zinc or gold-coat joist hangers, the DTB-TZ transfers
the lateral loads into the exterior wall while the joist hangers support
the vertical loads. The DTB-TZ can also be used to reinforce the
connection between the rail post and the deck.
