  • Construct your deck with safe, cost effective connectors
  • No need to access the floor joists inside the house
  • Stronger and safer than nails, lag screws or bolts
The DTT2Z is a safe, cost-effective way to attach deck-railing posts to the deck framing for stronger, safer railings. Because the post is tied back into the deck joists, rather than to the rim joist alone, the connection is stronger than typical through-bolt installations. The DTT2Z is also ideal for guardrail-post connections and lateral-load connections between the deck and house.
  • Suitable for lighter duty hold own applications on single or double 2x posts
  • Ties the guardrail post into deck framing
  • Stronger and safer than nails, lag screws or bolts
  • Ties the deck into the house for a stronger, safer ledger connection
  • Helps prevent a common type of deck failure
  • Installs easily with Strong-Drive SDS screws (included)
  • Made from 14-Gauge steel
  • ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
  • Quantity: 2
  • Install with 1/4 in. x 1-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (included) and 1/2 in. machine or anchor bolt

Questions & Answers

I'm going to use these for fastening 4x4 deck railing posts to the outside of the deck rim boards...

I'm going to use these for fastening 4x4 deck railing posts to the outside of the deck rim boards, on 2 sides of the deck, where the rim runs parallel to the joists and also the side where the rim is perpendicular to the joists. A couple questions: (1) Is one fastener per post enough? (2) Is it ok to use a long rod (let's say 12" long) so I can attach the tie about 5" back from the rim instead of butting it up to the rim? Any reason not to do that?
Asked by: kurt
One is enough for posts along the edge. You probably will need two for the corner posts. Longer rods are fine. Take a look at this http://www.deckmagazine.com/design-construction/railings/code-compliant-guardrail-posts_o

What specific 1/2" bolt should be used with this? I see a washer is included and is that to go against the DTT2Z? Then I supply another washer for the post side?
Asked by: JustMe
Galvanized steel threaded rod should be used if used in deck construction, threaded rod size is 1/2" for deck tension tie.

Does the two pack for sku 251910 at $16 contain one or two of the metal fixtures?

It looks like the price is for a box with 2 fixtures. But when I said I wanted 2, the price showed up as $60.
Asked by: Bob
Each box is exactly as pictured- it has two brackets which will tie one joist or one post.
