Questions & Answers

If I want to use the Rtz42 ties so I can have 4x4 legs will the length or width dimensions of the 2 x 4 lumber change? I?m going off a set of plans but they are designed for the 2x4 brackets.

Answer This Question

Hello Charlie, this is McKenzie with Simpson Strong-Tie. The RTC42 is sized for a nominal 4x4 post (3.5") and nominal 2x joists or beams (1.5"). The link in your ask, is the RTC2Z sized for nominal 2x4 post and 2x joists.

    Would this work with 2x2 lumber or does the upright piece need to be 2x4

    The RTC2Z requires a 2x4 post. Thank you!

      No, these really need 2x4's to be able to function correctly

      Yes, they are galvanized sheet metal. I would do a self etching primer first before finished paint

      I recently used a primer on the metal beforeI painted with a latex paint. I will know as time goes on how durable it is.

        Can you use these as corner braces for a ground level deck? Knocking the point into the ground?

        Answer This Question

        It would be up to the Designer/Engineer of Record to specify the appropriate connector based on framing layout, demand loads, local building codes, etc., but I can tell you we can only support the installation of our products as designed/tested. In the case of the RTC2Z that would attached to a wood post and carrying the two size members. Also, other than the E-Z Spike, we do not recommend any of our connector products for below grade applications. Thank you!

        By|Jul 6, 2020

          Even though they are galvanized, I don't believe they would not last long with ground contact / weather

          Can you use it flipped over, with the extending piece facing up?

          Answer This Question

          It is designed for the extending piece to go along side the corner post. Then the 2x4 to set into the slots. You could place it on top of the 2x4's and add an upright post.

          By|May 16, 2023

            Yes, it can be used upside down. The attached picture shows the top of my work bench and if you wanted to have pieces at the bottom of the legs that can be done.

            I don't think why not. However, it should depend on the purpose. The design of the bracket is to have the short sides holding the lumber pieces and sustain the weight from the top layers. That is another reason the extended side facing down to provide extra support and forming a "strong math triangle" structure. If you flip it upside down, it would depend on your design and other bracket option might work better for your purpose.

              No. The whole point if this product is to support a 2X4 which will support the upper structure

                (1)

                If you did use it upside down, the only thing would be the support for your cross pieces would only be from the screws. You wouldn't have any structural support.

                Could you use this to connect two 2x6 beams at a corner, resting on top of a 4x4 post?

                Answer This Question

                No. You could probably use to connect 2x6 on top of a 2x4 post, but not 4x4. They probably make a different one for 4x4s.

                By|May 5, 2023

                  No, but they make a different version compatible with 4x4s that you could use 2x6s with for the sides. Model #RTC42

                    What you need is RTC44. I'm looking for a local vendor, myself (scarce for So CA). We have a project where we want to frame 4 x 4 x 4s and the RTC44 is perfect. You can go to https://www.strongtie.com, navigate to Locations to find a "Factory & Training Center" and put in some calls. I think HD will help you get it, too; it's just a special order.

                    By|Jul 31, 2019

                      For a 4x4 post you will want to use Model # RTC42 which will support a 2x6 beam, or any 2 by for that matter. Model # RTC2Z only support 2x4 posts

                        Yes, I suppose....but the connector is designed to allow vertical 2x4s to pass through. Your 4x4 obviously wouldn't do that. However, the connector could be used to attach 2 2x6s at a corner, and those could be attached to the top of a 4x4 post, as you suggest. I used the connectors to create a 4-shelf 8' x 8' x 2' shelving unit out of 2x4s and 2 4'x8' sheets of 5/8" A/C plywood, split lengthwise. Easily carries hundreds of pounds of tools and lumber. 4x4 legs sounds like overkill to me... Good luck.

                          Use RTC22Z instead. It is designed for 2x2 posts.

                            This model corner connector connects a 2x2, 2x3 or 2x4 vertical member to two 2x3 or greater horizontal members, forming a 90 degree corner.

                              I don't think so, they are specifically designed for 2x4s. There are several different connectors for 2x2...see the catalog via the link below. Not sure which ones home depot carries. http://embed.widencdn.net/pdf/plus/ssttoolbox/xd2mseqyql/C-C-2017-p355.pdf

                                Oh, you could attach a 2x2 to this, but you won't be happy with the results. The exposed edges of the tie connector will maim someone, eventually.

                                  These are for a 2x4 so the holes and bracing wouldn't line up very well. I don't think it would brace it very well. They do work great for 2x4's though

                                  Do you have a similar connector for 2x6 construction? Or will this one work?

                                    This connector will accomodate 2x6 for the horizontal members, but not the vertical members. I'm unaware of a similar connector that will work with 2x6 vertical members without going to a structural column cap.

                                        Nice brackets, though expensive. You can buy them in workbench kit of 8 with screws included, and that is what I recommend over buying them singly. It is cheaper that way. I used mine to build an aquarium stand (see picture). These are galvanized, so if you paint them you can't use most spray paint without a special primer. I used acrylic latex paint, which is supposed to work with galvinized metal. It took about 3-4 coats.
