Three Ergonomic Handles | Solid Cast Iron | Glossy Black Finish | Plate Loaded Machine Compatible
Product Overview
The SP007 Tri Grip Cast Iron Weight Plates are designed for versatility, durability, and user convenience. Featuring three ergonomic grip handles, these plates allow for easy lifting, loading, and maneuvering—eliminating the need for awkward pinching or struggling with smooth edges. Manufactured from high-grade cast iron with a glossy black finish, the SP007 combines the durability of traditional iron plates with the ergonomic benefits of multi-grip design.
Ideal for plate-loaded machines, selectorized equipment, power racks, and free weight training, these plates are a favorite among commercial gyms, CrossFit boxes, and home gym users who value functionality and ease of use.
Available in a full range from 2.5kg / 5lb to 25kg / 55lb, sold in pairs or complete sets, with bold weight markings and precision 50.4mm bores for universal compatibility.
