W240 Variable Reach

W240 variable reach top loading arms for chemical and industrial products are ideal for loading single or multiple compartment tank trucks, or rail cars where a small amount of miss-spotting (positioning) is required.

Variable reach loading arms have a secondary pipe and additional swivel joint that provides an extra plane of orientation once the fixed primary tube has been locked in to the fill position.
