Slater Stone Molds

The most durable Atlas Stone Mold in the strength industry, with a reputation of making excellent competition-grade Atlas Stones with ease.

Available here in 10 size options from 8" to 24" in diameter (an approx. resulting weight range of 23LB to 586LB), these dependable plastic molds are hand-made by experienced strength athlete Steve Slater and his team at Slater’s Hardware in Lancaster, Ohio. For years, Steve consulted with Strongmen, machinists, foundry workers, concrete specialists, contractors, and his own customers to help him perfect a design strong enough to produce as many as 50 clean, quality stones off of one mold.

Slater Molds have been trusted to create the Atlas Stones for the World’s Strongest Man competition, the Arnold Strongman Classic, and many other worldwide strongman/strongwoman events over the years. They’ve also been featured nationally on ESPN and The Today Show.

All Slater Molds come with easy-to-follow instructions, and enable any athlete (from beginners to seasoned pros) to save time and money while the mold does much of the work. Be sure to check out the video below, as Steve Slater walks you through the basics of "How To Make an Atlas Stone."

Please Note: All stone molds with the Slater name are hand-cut, as are the pour holes on each mold. Because of this, not every mold will be identical or perfect. Some molds may have a wavier seam-line than others, and some pour holes may not be perfectly round or might show a small entry mark left by a cutter. Slater guarantees, however, that no mold imperfection will impact the quality of the stones a customer is able to produce. In the unlikely event that it does, customers can contact Slater or Rogue to set the situation right.

Rated 5 out of 5 by from Makes a good quality stone Simple to use and works as advertised. Follow the directions and be sure to take a lot of time to vibrate the bubbles out.

Rated 5 out of 5 by from Awesome stones! I have purchased the 10” and 12” stone molds. They were easy to make with the great YouTube video. I got the concrete from Lowe’s and the fibers and bags from amazon. I let mine sit for 5 days. They turned out great! Mine ended up being about 5 pounds lighter than stated. Very durable. I’ve used them in a few workouts now and very pleased!

Rated 5 out of 5 by from All around rigid product Purchased a 12" Slater Mold, yeah I know its only 72pounds, but I gotta start somewhere, right !!!! Love, Love, Love it. Only thing is, being from Canada, those fibre additives aren"t easy to find, and because I ordered it right from Rogue instead of Slater I was not aware I could order them. Just a note, to increase your add-on sales.

Rated 5 out of 5 by from Pretty good stuff I bought the 16" stone and I wish I'd bought the 18". That was my mistake, but the mold works well. There's about a 1/2" seam where the mold meets, but that just seems to be a superficial thing. Some light sanding around the seam made it just fine. The only thing I'd note is that the vertical line showing where to line it up is just sharpie. It's not a big deal, just thought you should know it's not permanent.

Rated 5 out of 5 by from Up to Reputation I only have the one mold so far, but I've made several stones from it and I didn't have a problem with any of them! Looking forward to making my next purchase when I can't possibly fit any more inserts in my next stone!

Rated 5 out of 5 by from You wont be disappointed! Slater's molds are bar none the best I have ever used! I have a couple smaller sizes from their competitor and they do a decent job, but the Slater molds make a much cleaner stone and leave hardly any excess lip where the two pieces of the mold meet. I have turned out a ton of stones with these molds and they show no serious signs of wear and tear. I highly recommend these molds.
