Customizations:

• We offer custom stone mold lettering, limited to 25 characters, allowing for personalization or branding of the stones. Customization can be added to your order by adding “Custom Stone Mold Lettering” to your cart through our product page. Custom Lettering comes in the form of a sticker placed on the inside of the mold, which will leave an impression on the completed stone. Custom Lettering is only guaranteed for one atlas stone. 
  

A Note From Slater Strength,

Since our inception, the Slater Atlas Stone Mold has been meticulously handcrafted in the basement of Slater’s Hardware. With the closing of the hardware in early 2024, the Slater Atlas Stone Mold is still made in Lancaster, OH, but now at the “Slater Warehouse”. Steve Slater and his family continue to personally produce Slater Stone Molds, and we are committed to maintaining this tradition. Despite our growth, we have resisted switching to outsourced manufacturing processes, opting instead to keep production local, providing employment opportunities to our family and community members. Our pledge is to deliver a product capable of crafting stones worthy of prestigious events like the Arnold Classic and the World’s Strongest Man competition. If ever our product fails to meet your expectations, we will make it right – no questions asked.  

Include our large-poly, super-strong polypropylene/polyethylene blended synthetic macro-fibers in your concrete mix to assure the strongest possible stone. These fibers act like mini re-bar, successfully replacing steel fibers, welded wire mesh, and conventional reinforcing bars in the stone. Fibers increase overall durability, fatigue resistance, and flexural toughness of the stone. Bulk mixture includes (1) 12oz bulk bag or box of fibers, equivalent to around 8 small bags of fibers. 

Small Bag - Include with wet concrete mix:

• 8"-12" Stone: 1/2 Bag
• 14"-18" Stone: 1 Bag
• 20"-24" Stone: 2 Bags

Bulk Box - Include with wet concrete mix:

• 8"-12" Stone: Small Handful
