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.

Slater Stone Molds is rated 4.8 out of 5 by 20.
Rated 5 out of 5 by from Easy to use Got this a month or so ago and have made 2 stones. The first was too smooth and my concrete was too runny. Watch the Slater video. Second time I dug a small indentation in the ground rather than using a bucket. Also use the bag for mixing. I use empty grain bags from a brewery.

Rated 3 out of 5 by from Mold defects Order two different size molds after I was pleased with my very first mold. How ever the 2nd two I got were both dented I didn’t think much of it and poured the concrete and my 16 inch stone has a big enough dent that I may not make anymore

Rated 5 out of 5 by from Great molds This is my second Slater mold. Both have been excellent. Easy to use and reusable even after drilling to add lightening kits. I have made multiple stones of varying weight with both molds. I finished one with grinding of the 'stem' and filling with concrete sealer, but found both unnecessary and use the stones as they come out of the mold (I do take appropriate care to remove bubbles when molding). Highly recommended.

Rated 5 out of 5 by from Perfect stone! Bought this about a month ago. Took a couple weeks before it even shipped but that’s because they make them after the order is in; also hand made by the slater company so I didn’t mind the wait. I followed their instructions and also watched a couple you tube videos on how to use the mold properly and the stone came out perfectly! Very very minimal seem in the finished product due to the molds construction. I kept it just slightly under filled so the stone would have a small flat spot which is great because it doesn’t roll around when not in use. Overall very pleased with the mold and I will definitely be buying the next step up in size (after I can comfortably throw this size around first).
