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
  • 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

Can simpson screws be used with pressure treated wood

Asked by Me May 23, 2021

Answers

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.

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

Asked by JustMe August 31, 2017

Answer

You could try and use one of Simpson's narrower tension ties and install it on the bottom of the 2x6, which, depending on the center line dimension, could increase the distance between bolts anywhere from 3/4" to 1-1/2". The DTT1Z is intended for installation on the narrow face of a joist, however if this doesn't get you the loads you need the LTT19 is narrow enough to fit on the narrow face of the joist (at the underside). If the configuration works, you could also add blocking to widen the joist and use something heavier, such as the HDQ/HHDQ series.

Asked by JustMe August 31, 2017

Answers

I placed a guard post on a flat surface and marked the location of the top bolt hole using a DTT2Z. I then measured 2" from the bottom of the post and marked the location of the bottom bolt hole. Then I set up stops on my drill press so that I could drill all of the bolt holes in all of the guard posts. Finally, while installing a guard post, I clamped the post to the rim/band joist, plumbed it, and then drilled through the joist using the holes in the clamped guard post as guides. I was able to drill all of these bolt holes from below my raised deck.

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!

I used these to strengthen railings on my deck to meet lateral force requirements. They work great. The railings are much more resistant to lateral force and dramatically improve safety.
