We’re proud to introduce a new addition to MPI’s manufacturing lineup—precision-engineered parts for the LocknLoad Chock system, a specialized solution used in bi-level autorack railcars to prevent vehicle movement
during transit.

This innovative chock system is designed for fast, tool-free installation and removal, featuring a release lever, a visual engagement indicator, and broad compatibility across multiple chock models. It plays a key role in safely securing both traditional and electric vehicles throughout rail transport.

Why the LocknLoad Chock Stands Out:

Enhanced Safety
Prevents vehicle shifting during transport

Universal Storage Solution
The Storage Pan mounts directly to autorack side screens and accommodates all bi-level chock models

Durability
All-metal construction with corrosion-resistant coating

Efficient Operations
Easy install/uninstall and aftermarket support

EV Ready
Proven performance beyond standard AAR handling requirements

Parts Manufactured by MPI for the LocknLoad Chock System:

Universal Storage Pan Assembly
Built for strength and corrosion resistance, this component ensures secure stowage of chocks when not in use.

Hex Shaft – Long Version
Designed to deliver optimal support and torque transfer in the locking mechanism.

Fixed Teeth
Manufactured for reliable grip and engagement within the chock interface.

Lifter Arm
Enables smooth activation and deactivation of the locking system.

Locking Teeth
Engineered for firm locking performance under high dynamic loads.
