Overview
The DA Tempering Roller Mold is a collaborative innovation between Stix and Stone and powerlifting legend Donnie Thompson. Designed to make "Body Tempering" accessible and affordable, this vacuum-formed plastic mold allows users to cast their own weighted rollers using concrete. Body tempering is a heavy-duty myofascial treatment that uses external weight—rather than body weight—to break up trigger points and relieve muscle tightness, offering a significant upgrade over traditional foam rolling.

Key Features and Specifications
Construction: Interlocking, heavy-duty vacuum-formed plastic (Black).
Design: Based on the professional DT Tempering Roller design by Donnie Thompson.
Dimensions: 24” (Outside Length) x 8” (Outside Diameter).
Mold Weight: 3.25 LB (Unfilled).
Finished Capacity: Holds approximately 100 LB of 5000 PSI concrete.
Reusability: Engineered for multiple concrete pours to build a full library of rollers.
Origin: Made in the USA (Ships from Texas).
Performance Benefits
Passive Recovery: Unlike foam rolling, which requires supporting your body weight, tempering allows you to lie relaxed while the weighted roller provides passive pressure to the joints, muscles, and fascia.
Customizable Weight: Users can adjust the final weight of the roller by mixing in scrap steel/lead to make it heavier or using a foam center to make it lighter.
Cost Efficiency: Provides a professional-grade tempering solution at a fraction of the cost of cast-iron rollers; the cost per roller decreases with every pour.
Intense Mobilization: The 100 LB weight (standard) creates intense soft tissue mobilization that penetrates deeper into muscle bellies than standard rollers.
Maintenance and Care
Casting Instructions: 1. Prep: Clean the mold with isopropyl alcohol and lube both sides with paste wax or silicone spray. 2. Assembly: Fit the male half into the female half and seal the entire seam securely with heavy-duty duct tape. 3. Pour: Set the mold vertically in a bucket of sand for stability. Layer concrete (high-strength +5000 PSI recommended) and vibrate the mold to remove air bubbles. 4. Reinforcement: It is highly recommended to insert (2) 18” lengths of rebar into the wet mix for structural integrity.
Demolding: Wait 2–3 days before removing the tape and carefully lifting the mold halves.
Curing: Let the concrete roller cure for at least one week before light use; full strength is typically reached after 28 days.
Cleaning: Immediately wipe the mold clean with soap and water or alcohol after each pour to prevent concrete residue buildup.
Storage: Store the plastic halves in a cool, dry place away from direct sunlight to prevent warping.
Warranty Information
Rogue generally warrants Stix and Stone products for construction and material defects at the time of purchase.
Note: The warranty does not cover damage caused by negligent use, improper concrete mixing, or failure to properly secure/lube the mold during the pouring process. Cosmetic imperfections in the finished concrete (such as air bubbles) are a result of the pouring technique and are not warrantable defects.
Frequently Asked Questions
Q: How do I make the roller smoother? A: You can use a back massager or agitator against the mold during the pour to bring air bubbles to the top. After demolding, you can rub a slurry of extra concrete into any holes and sand the surface for a smooth finish.
Q: Can I use regular concrete from a hardware store? A: Yes, but for the best durability and weight accuracy, a high-strength mix like Quikrete 5000 PSI is strongly recommended.
Q: How many rollers can I make with one mold? A: With proper lubrication and careful demolding, a single plastic mold can be used for dozens of pours.
Q: Is the rebar necessary? A: Yes. Without internal rebar reinforcement, a concrete cylinder of this weight can be brittle and may crack if dropped or handled roughly.
