Ultimate RB Rubber Recycled Rubber Gym Flooring

Ultimate RB Rubber Ultimate-Tough™ TRU-LOCK™ Interlocking Rubber Gym Tiles – Ultimate-Tough TRU-LOCK tiles from Ultimate RB Rubber are 2' x 2' gym flooring tiles which interlock on all four sides to create flooring solutions in residential and commercial applications. 5/16" (or 8mm) thickness is a great option for medium-duty flooring applications where durability is required but impact from dumbbells and plates may not be as great and budget may be a concern, since they are generally less expensive and lighter to ship than standard 3/8" rubber gym tiles. The TRU-LOCK tile is designed to cover 4 square feet per tile, which makes estimating the quantity of tiles needed simple when sizing your project and placing an order. TRU-LOCK tiles are engineered precisely with an intricate interlocking pattern which reduces the visibility of tab seams as the tiles are installed. The tab design holds the tiles together securely without the need for expensive adhesives, tapes, or the labor to apply them. Simply lay them out like a puzzle and self-trim at walls with a straight-cut edge for a finished look. The TRU-LOCK tiles can also be disassembled and re-assembled time and again without damaging the tiles. On top of that, they are also very easy to clean.

TRU-LOCK rubber flooring tiles offer both sound and shock absorption qualities and they can also serve as an effective vibration buffer. TRU-LOCK tiles are great for anti-fatigue resistance. Fabricated from fine rubber granules, they give superior underfoot comfort to cushion the strain from running, exercising, and walking. Custom-formulated, high strength polyurethane binders, similar to those used in synthetic running tracks, are used in the construction of Ultimate RB products. When they are combined with recycled tire crumb in the unique manufacturing processes, an extremely durable material is produced. TRU-LOCK is a cost-effective investment designed to last for years as commercial-quality gym flooring, a doggy daycare solution, and walkway covering vastly superior to lesser-grade foam tiles and the like commonly found at home improvement centers, warehouse stores, and big-box retailers.

TRU-LOCK Interlocking Rubber Flooring Selections:

  • 24" x 24" x 5/16" tiles – Solid Black for simple, solid visual floor appearance and most economical purchase (no purchase minimum applies)
  • 24" x 24" x 5/16" tiles – 10% Color Fleck to add feature color and help hide dust, dirt, and footprints (minimum purchase quantity 25 tiles)

NOTE: Solid Black, Blue Fleck, and Grey Fleck tiles are most popular and tend to have shorter production lead times than other color options since they are more frequently on the production schedule
