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
  • 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
  • Install with SDS 1/4 in. x 1-1/2 in. screws (included)

Rated 5.0 out of 5.0 by Product solves big problems I was selling my house and the guy that was inspecting it noticed that the deck was pulling away from the house. Not being in the construction business, I figured it was going to be a prolonged and very costly repair. After discussing the problem with the Pro at Home depot he showed me these do-hickeys and in a couple hours the problem was resolved. They didn't pull the deck back to where it originally was, but they anchored it to the house so that no further separation would occur. I used a set on each end of the deck and one in the middle between the deck and the house They seemed a bit pricey for a couple of brackets and some bolts, but for the solution they provided they were a steal.. Thanks Home Depot.. August 25, 2015
Rated 5.0 out of 5.0 by Works as advertised I bought these to attach railing posts to my deck and also to attach the joist at each end of the deck through the ledger board to one of the floor joists inside the house (per code). They work very well. September 8, 2015
Rated 5.0 out of 5.0 by A must for railing installation!! I have been installing decks for many years, this produce was used for 2 Purposes in my last installation. 1 to add additional strength to an existing ledger and 2 to properly secure a railing on a deck that would be over 30' above grade. This product was easy to install and exceeded my expectations. The railing system has little to no deflection and I am certain of the safety the product provided. October 8, 2013
Rated 5.0 out of 5.0 by A must for deck railing posts I rebuilt my deck and added new railings to the deck with these Deck Tension ties. They really do a great job of strengthening how you attach the railing posts to your deck. I highly recommend these to make your deck safer. April 30, 2011

Rated 5.0 out of 5.0 by Pricey, but works as advertised All these heavier metal,connectors seem way over-priced no matter where u go...but it does work as indicated and does a nice job locking posts tight. Be sure to go back and tighten all the connectors after the wood is thoroughly dried out. August 21, 2012
