Overview
Slater Stone Molds are widely recognized as the most durable and reliable Atlas Stone molds in the strength industry. Hand-made in Lancaster, Ohio, by Steve Slater and his team, these molds have been used to create competition-grade stones for elite events such as the World's Strongest Man and the Arnold Strongman Classic. They offer a cost-effective way for athletes and gym owners to produce their own professional Atlas Stones with a consistently clean, seam-free finish.

Hand-Crafted: Molds are hand-cut; slight variations in seam lines or pour holes are normal and do not affect stone quality.
Origin: Made in the USA.
Performance Benefits
Professional Grade: Trusted by the highest levels of Strongman competition to provide perfectly spherical, competition-ready implements.
Cost Efficiency: Allows any athlete to build a full set of Atlas Stones for a fraction of the cost of buying pre-cast rubber or concrete stones.
Customizable Density: By using different concrete mixes or adding internal weight (like lead shot) or lightening agents (like foam inserts), users can customize the final weight beyond the standard diameter estimates.
Seam-Free Results: When preparation instructions are followed, the molds produce smooth stones that require minimal finishing work.
Maintenance and Care
Setup: For stones up to 18" in diameter, a 5-gallon bucket can be used for support. For larger stones (20"+), it is recommended to support the mold in a sand pit or a custom cradle to prevent flat spots or indentations.
Release Agent: Always use a proper release agent (like vegetable oil or specialized spray) inside the mold before pouring concrete to ensure easy removal and a smooth surface.
Cleaning: After stripping the mold from a dried stone, scrape away any excess concrete bits. Wipe the interior clean and store in a cool, dry place away from direct sunlight to prevent the plastic from becoming brittle.
Inspection: Before each pour, check the mold for cracks or significant warping. Small surface dents can often be pushed back out, but structural cracks may affect the stone's shape.
Safety Note: Concrete work requires proper safety gear, including gloves and eye protection. Follow all curing time recommendations before attempting to lift or drop a newly cast stone.
Warranty Information
Slater Stone Molds are manufactured to high standards of durability. Slater guarantees that minor mold imperfections (like wavy seam lines) will not impact stone quality.
Note: If a mold has a defect that prevents the production of a quality stone, customers should contact Slater or Rogue for a resolution. Warranty typically does not cover damage caused by improper support (e.g., bucket rings on oversized stones).
Frequently Asked Questions
Q: How many stones can I make with one mold? A: With proper care and the use of release agents, one Slater Mold can produce 50 or more Atlas Stones.
Q: Do these molds come with instructions? A: Yes, all Slater Molds include easy-to-follow instructions. Steve Slater also provides a "How To Make an Atlas Stone" video tutorial available on the Rogue website.
Q: Why is my stone heavier than the listed weight? A: The weights provided are approximations based on standard concrete density. Variations in concrete mix, water content, and internal fillers will cause the final weight to fluctuate (often +/- 30 LB on larger sizes).
Q: Can I pick these up at the Rogue store? A: Currently, Slater Molds are available for shipping only within the CONUS 48 states; in-store pickup is generally not available for this item.
