Product Overview

  • Features 14-gauge steel construction for strength
  • Galvanized finish is corrosion resistant for durability
  • Designed for fast and secure installation
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)

Questions & Answers

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
The kit contains two as shown above, and the proper application of the product requires 2 as well.

FYI the "info and guides" PDF doesn't include this product. Where can I find the correct guide?

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
Correct- they don't supply the hardware for the opposite side since that's a variable, so it's up to you to select the correct length of bolt, nuts & washers (with the exception of the washer provided, to be used at the tension tie side), or if these are used in shear wall applications they would use a different anchor. Make sure you use galvanized hardware since it will both hold up to the weather and be compatible with the ZMax finish of the DTT2Z. I'd suggest a standard through bolt or threaded rod cut to length versus a carriage bolt since using a washer will increase the bearing area on the outer post side.

can these be used to help secure and attach joists that are separating from a ledger board
Asked by: starben62
Yes, however based on the picture you should make sure that there's still enough bearing on the hanger seat, which may have to be removed & replaced, possibly with one with a longer seat (unless you can take up some of that slack with the tension tie). Given the center line dimensions of the bolt hole in relation to the hanger flange, you may need to screw some blocking to the side of the joist so that it will clear the hanger flange...one problem to deal with is that you won't be able to nail the flange on that side once the DTT2Z is in place, so you may want to use screws instead of nails (on the hanger flange) with an extension on your drill bit in order to get around the DTT2Z. I'm not sure what the flashing situation is there, so I suggest using a lag screw with just enough penetration to bite into the ledger board without going any further.

ZMAX 14-Gauge Galvanized 2x Deck Tension Tie (2-Pack) with SDS Screws is rated 4.8 out of 5 by 30.

The DTT2Z is a superior product - heavy duty and it was quite easy to install. I installed two sets on a deck and plan to put another one to tie to the floor joist in the basement.

Piece of cake to use, and made for a super-strong deck railing. I attached these to the stringers about a quarter inch from the outside rim joist. Then I drilled a hole for a 1/2" carriage bolt through the post, the rim joist and through this device. All that is left is to snug up the bolts and it was rock solid.

Rated 5 out of 5 by from 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..

Rated 5 out of 5 by from Post fastening system Using the Simpson Strong Tie Deck Tension Tie is the only way to meet and exceed the IRC and IBC requirements for a 200lb live load. Much better than blocking the posts. I always pass inspection (s) when I use this system.
