Product Overview

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)

Customer 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: Anonymous
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?

Won't the location of the ties interfere/overlap with the joist hangers?

.
Asked by: JohnnyHomeowner
It most certainly could, and you must adapt your assembly as necessary. Skip the joist hanger where the posts are and use an 'L' type bracket on one side of the joist and the tension tie on the other. Just a suggestion...

Is there a DTT2Z deck post connector for 5/8" - diameter bolts?

The Simpson DTT2Z-R2 shows a 1/2" - diam. machine bolt; if the engr has specified 5/8"-diam. bolt, is there a different Simpson DTT2Z?
Asked by: Jeff
You should ask the engineer for clarification- if the loads require a 5/8" diameter rod, you may need to bump up the tie to an HDU2-SDS2.5 or one of the many options Simpson has...or it could have been a type-o and the 1/2" is fine.

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 The wood will break before these give You need these to harden the connection between the pillars and the joists if you want your deck to be to code. The only deflection you'll get from the pillar is from the bending of the wood with these properly installed. You could have a party of "large" people leaning against all of your rails simultaneously and you would not need to be concerned about their safety. I recommend getting a 3/8" socket adapter for your drill to make installing the 8 screws quick and easy.

Rated 4 out of 5 by from 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!

Rated 5 out of 5 by from Strong Ties for Solid Feeling Posts Converted a spindle-only deck railing to 4x4 post-and-spindle design. Once I figured out how to drill the rim joist holes to line up with the Simpson ties, it went quite fast. Using half inch bolts sounded like over-kill, but the railing is very solid, so guess the engineers knew what they were doing. Very satisfied with the conversion. This design gives me a 3.5 inch horizontal space under the railing to blow leaves through.

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.
