Commercial-Grade Urethane | 3-Hole Grip Pattern | German Polyurethane | Laser-Engravable for Custom Branding
Product Overview
The WP109 Tri Grip Urethane Olympic Plate represents the gold standard in commercial gym equipment—engineered for the demanding environments of high-traffic fitness facilities, military bases, university recreation centers, and corporate gyms. Constructed with a high-grade cast iron core and encapsulated in odorless, impact-resistant German polyurethane, these plates deliver unmatched durability, safety, and long-term value.
The functional 3-hole grip pattern enables easy loading, offloading, and versatile exercise applications—from deadlifts to weighted carries. Unlike painted cast iron that chips and rusts, or rubber-coated plates that dry out and crack, urethane maintains its hard-wearing durability and premium aesthetics for years, offering commercial operators a superior return on investment.
Available in LB increments from 2.5lb to 45lb, sold in pairs or complete sets (280lb, 600lb, 1190lb configurations), with custom laser engraving and polyurethane color options available for facility branding.
