Spark-Proof Urethane Heavy-Duty Single Wheel Chock (Exposed Rail)

Product details

Aldon’s SPARK-PROOF urethane single chock is designed for freight-car and locomotive applications where a non-sparking chocking material is needed. The resilient urethane compresses and recovers its shape, resists many chemicals, and uses transverse ribs to displace water and dirt at the rail contact.
