Slater Stone Molds

Slater Stone Molds are hand-made Atlas Stone molds produced by Steve Slater and his team at Slater’s Hardware in Lancaster, Ohio, sold through Rogue Fitness. They’re the molds behind the Atlas Stones used at World’s Strongest Man, the Arnold Strongman Classic, and numerous other worldwide strongman and strongwoman competitions. The lineup spans 10 diameters from 8” (~23 lb) to 24” (~586 lb), letting a gym build out a full progression of stones from one manufacturer. Each two-piece plastic mold is rated to produce roughly 50 stones before it wears out, and yields a seam-free, competition-grade finish once the concrete cures and the mold is tapped apart. Independent reviewers and hands-on YouTube comparisons consistently find the Slater mold seals tighter and finishes smoother than its main rival, Hybrid, though its thinner plastic means the mold needs to sit undisturbed (ideally cradled in a tire) during the multi-day cure to avoid picking up an indentation.

What is a Miscellaneou?

What’s in Miscellaneous

This is the catch-all for the conditioning tools and accessories that don’t fit a single equipment class — weighted vests and plate carriers, medicine and slam balls, plyo boxes, ab mats, and the odds and ends that round out a garage gym. Items land here because their job (loaded carries, jumps, core work) cuts across the categories rather than sitting neatly inside one.

Who it’s for

Anyone filling in the gaps around the big pieces. If you already have a rack, bar, and plates, this is where you find the vest for rucking and weighted push-ups, the ball for slams and wall throws, or the box for step-ups and box jumps. Match the tool to the training you actually do — a plate carrier for conditioning and rucking, plyo boxes for explosive work — rather than buying the whole shelf.

Slater’s Atlas Stone molds are the industry benchmark — the same molds used to build stones for World’s Strongest Man and the Arnold Strongman Classic — and independent testers back that reputation up: GymRadar users rate them 5.0 across nine reviews, and both Garage Gym Builder’s review and a side-by-side YouTube pour found the Slater mold seals tighter and finishes smoother than its main rival, Hybrid, with less cleanup after the pour. Functionality is the standout — 10 sizes spanning 23 to 586 lbs from one manufacturer, each mold rated for roughly 50 pours. Build quality is the one caveat every independent source flags the same way: the plastic runs thinner than Hybrid’s, so the mold needs to sit undisturbed (ideally cradled in a tire) during the multi-day cure or the stone can pick up an indentation.

  • +Functionality: produces seam-free, competition-grade stones in 10 sizes from 23 to 586 lbs (Rogue product page)
  • +Build quality: tighter seal and smoother finish than Hybrid molds, confirmed in a side-by-side pour by an independent YouTube reviewer and by Garage Gym Builder's review
  • +Durability: rated for roughly 50 pours per mold before replacement (Rogue product page)
  • +Value: cheaper than Hybrid's competing mold range while covering a wider size spread (Garage Gym Builder)
  • Build quality: thinner plastic than Hybrid means the mold must stay undisturbed during the multi-day cure or the stone can pick up an indentation (Garage Gym Builder)
  • Versatility: smaller pour opening than Hybrid makes filling and air-bubble removal more fiddly (YouTube: Alan Thrall / Untamed Strength)
  • Value: GymRadar's independent sample is still thin (9 reviews), so the 5.0 average isn't yet a large-scale verdict
