About This Product

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.

Highlights

  • Suitable for lighter duty holdown 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

    Q:What is the difference between this with two in the DTT2Z-R2 box for $30.78 and the single deck tension tie at $10.44 DTT ZMAX???

    Answer This Question

    A:  Quite a lot, actually. The DTTZ has a tension load of 840-910 lbs, depending on fasteners used. The DTT2Z has a tension load of 1810-2145 lbs. So you would need to used fewer DTT2Zs to start with. Secondly is their method of attachment. The DTTZ uses a lag screw to attach it to the house, ideally shot into the double top plate of the exterior wall - can take some adjustment to make certain you hit that area. You used to be able to screw into the rim joist, but that does not have nearly the capacity of the double top joist. Additionally the DTTZ usually is quite easily screwed into the bottom of a deck joist. The DTT2Z is attached to the side of a deck joist, and the other half usually will be placed on the side of an interior floor joist, meaning cutting a hole in the sheetrock to access the floor, or ceiling, joist. You can use them for other purposes around the deck, such as post installation, and in some cases will only use one, and on the other end of the threaded rod or bolt use a bearing plate and nut. But that is the other big difference, which is the use of a threaded rod instead of a lag screw. I always use stainless threaded rod, along with stainless nuts and washers, depending on the application. So they have different uses and the DTT2Zs often are used in pairs, but have substantially greater capacity concerning lateral loads. If I am doing a deck retrofit I use DTTZs, and usually 50% more than called for - local jurisdiction here requires two at each side and then two in the center area, but depends on the size and height of the deck. For a 500 square foot sunporch I built that was 10' up in the air the building department allowed me to use a DTTZ on every floor joist - 16" centers - as the primary load-bearing attachment to the existing house, but that is a local decision. For new construction that has not been sheetrocked I use the DTT2Zs. Strong and you can be 100% certain that deck isn't going anywhere.

            Q:Looking for the correct 1/2-inch galvanized threaded rod to use with these DTT2Z connectors. Is Home Depot Store SKU #1005222583 the right one? It's in the electrical department, which made me wonder.

                A:  Yes, everything in this kit is galvanized and ready for use with pressure treated wood

                A:  Yes, I installed on my deck last year and I had a great experience.

                by|Sep 11, 2023

                A:  It's designed for decking and railings so yes otherwise this would be a poor choice by the manufacturer. Screws are galvanized and drive easy with an impact driver. You will need a lag bolt and nut.

                  First of all this kit can be used in various situation besides just it's direct purpose as a deck tie. Evening is of very good quality, nicely packaged. The best part is that this kit is more cost effective compared to buying all parts separately, also price is lower than at the lumber yard. Just keep in mind that you would have to purchase a threaded rod and hex nuts separately if you plan to use it as deck tension tie.

                  Good, but Interference with Joist Hangers
                  Used these to support 42" railing posts on 2x10 framing. You have to modify the install slightly for 36" vs 42" railing (see L-C-GRDRLPST4215). The problem we had was the instructions mention nothing about interference from the joist hangers. The bolt would go through a substantial portion of the hanger! So we nailed on a 1x board between the joist and the tension tie to space it out far enough. Is it as strong? I hope so!

                  They worked well only prob I found is the screws that came with them tended to strip out very easy I think they should have been threaded all the way instead of half way up

                  Do not buy the two pack! Buy the single one.
                  This is a very good product, but I don't understand why the double pack cost ($29.78) 1.5 times more than the single one ($10.44). Shouldn't the double pack be less expensive than the single? I hope HD fixes this.
