The HSP-T4 is square tool made of steel that slides over the Oz-Hammer (OH-01) and keeps it centered on the inside of the Oz-Post sleeve when installing the T4-600 & T4-850. This Hammer Spacer is used in conjunction with the OH-01 Oz-Hammer. The OH-01 Oz-Hammer is 2 in. in diameter. The T4-850 and other models mentioned above are a minimum of 3-1/2 in. inside diameter so we recommend using the HSP-T4 to keep the Oz-Hammer (OH-01) centered in the Oz-Post sleeve during installation.

  • Use with T4 series post anchors
  • 1-Piece each
  • Powder coated tool
  • Long lasting reusable tool

Rated 4.5 out of 5 by 6 reviewers.
Rated 3.0 out of 5.0 by Just "okay." Well, I will say that this product is a absolute "must have," if you,plan on using the oz-post fence system. In order to hammer in the oz-post, you need a cut off piece of 4x4 and this little metal device must be used as a "spacer" when hammering. If you don't use the hammer spacer, your 4x4 wood piece will destroy itself after a few hammer blows. As far as the hammer spacer tool itself, well it isn't string enough. The corners of mine bent! I was surprised. It's only about 3/16" thick when it should be at least 1/4". Although thin, it will get the job done. It just should be a tad thicker to handle big sledge hammer blows.

Rated 4.0 out of 5.0 by good to have for oz posts you can get away without using this, but you better have another block that can take a beating and fits inside the oz post, or you will spend all day getting the driver blocks out of the post. With the sledgehammer method you really want this or something metal you have on hand that works, or you will have lots of lost time and wasted work. For 7 or 8 bucks I'd say get it. July 7, 2015
Rated 5.0 out of 5.0 by Works as advertised Worked great for what it is. Used with sledgehammer to pound in spikes in conjunction with chunk of 4x4. Each chunk of 4x4 probably lasted for 3 spikes (T4-850's) June 13, 2012
Rated 5.0 out of 5.0 by Performed as advertised This spacer is essential to keeping the jackhammer and the special OZ Post shank centered in the post socket. After driving nearly 40 posts in extremely hard clay soil, the spacer was barely scuffed from all the action. May 7, 2011
Rated 5.0 out of 5.0 by Unbreakable and works perfectly. Delivered to the house on time. Will last literally for ever. July 24, 2012
