1. Premium Heavy-Duty Rubber & Stepped Anti-Slip Design
Molded from high-density, weather-resistant industrial rubber. Features a robust stepped surface structure that significantly maximizes friction and grip against tire treads, preventing dangerous vehicle rollback.
2. Optimized Compact Specifications (4kg Solid Support)
Engineered to exact dimensions of 250 x 205 x 265 mm with a solid weight of 4kg. This optimal size-to-weight ratio provides maximum stabilization for heavy loads while remaining easy to deploy and store.
3. Universal Industrial Commercial & Fleet Applications
Perfectly suited for logistics hubs, loading docks, construction sites, and aviation ground support. Designed for securing trucks, trailers, RVs, and utility vehicles under all extreme outdoor weather conditions.
4. Factory-Direct B2B Advantages & Quality Assurance
Sourced directly from our professional manufacturing facility to ensure competitive wholesale pricing and stable supply. Integrated metal eye-ring allows for easy chain connection, theft prevention, and quick manual retrieval.
5. Flexible OEM/ODM & Custom Branding Support
We offer full customization options for international buyers, including molded custom logos, embossed branding, custom color stripes, or specialized weight adjustments to meet localized safety regulations.
Engineered with premium weather-proof vulcanized rubber to provide maximum safety at loading docks, logistics hubs, and construction environments. Prevent hazardous vehicle rollbacks with our high-traction, multi-size rubber block configurations.
Standard chocks crack or slide on smooth concrete surfaces. Our heavy-duty molded compounds absorb impact while delivering reliable tire immobilization.
Avoid UV degradation, oil rot, and freezing cracks. Engineered for continuous outdoor exposure in heavy rain, extreme heat, or sub-zero loading zones.
Outfitted with solid integrated steel handle rings and molded slots for fast manual deployment, anchor positioning, and chain theft-prevention.

Raw premium rubber polymers are processed under intense heat and high-tonnage hydraulic presses to achieve precise physical densities and uniform tensile strength.
Steel hardware and handle loops are mechanically integrated directly during the core curing stage, ensuring the ring never detaches under extreme pull forces.
Advanced tread design maximizes tire-to-chock contact area, effectively distributing heavy mechanical weight down to the road bed.
Cut intermediate traders and agents to directly maximize your wholesale margins and procurement budgets.
High daily output capacity backed by massive automated compression molds ensures your large-volume bulk orders are shipped on tight timelines.
Every batch undergoes intensive compression load testing, Shore A hardness confirmation, and impact testing prior to export clearance.
