Aldon 4011-36 Single wheel chock exposed rail with flashing light
• Why risk derailment or ruptured hoses if the night switching crew doesn't notice that a car wheel is still chocked? Aldon flag wheel chocks are now available with quick flashing light and mounting bracket.
Double Chocks
• Always use tarp strap (supplied with chock) to draw chocks against wheel. Replace strap if missing.
