Bronze plated piston rods resist scoring, and each ram can be "dead-ended" at full capacity for maximum safety. Has an angled coupler port (5 degrees) for easy hook up. Stroke: 1-1/2". Extended height: 5". Retracted height: 3-1/2" Forcing a gravity return ram to retract wastes both time and money. This OTC single-acting, spring-return ram eliminates that waiting. With the low collapsed height and the stroke you really need, this ram is ideal for a variety of applications.
