WHACK ‘EM Severe Duty chocks have reinforced steel handles that will not bend from hammer blows or extreme handle pressure. These cast steel chocks feature original heat-treated spurs for excellent rail-gripping power. WHACK ‘EM chocks are available in exposed rail or flush rail styles, single or double chock, with or without flag. The chocks are low profile (less than 3“ above rails) and fit all rail sizes and wheels from 28” to 42” diameter.
Look for the Red Handles!

Idling locomotives and tank cars are subject to greater vibration and potential wheel movement when chocked than other rolling stock. Chocks with rail-biting spurs can get stuck under the wheels. It can be very difficult to free a chock without resorting to force. Ordinary chock handles can bend when forced.
