Model 88: 3 Ton Single Acting Air Impact Marker

Model 88 3-TON: The Columbia model 88 impact marking cylinder is a rugged air cylinder with a built in stamp holder at the rod end. The 88 delivers a powerful impact blow of up to 3-tons at 80 psi. The patented shock absorbing bumpers at both ends of the stroke prevent damage to the marker when bottoming out on the forward stroke and reducing the shock on return stroke. The model 88 is a dependable marker at a very low investment cost. The rod has a spring return action while an efficient pressure venting system allows an instantaneous return stroke. Model 88 air impact markers have a keyed non-rotating rod and 2.5” of stroke.
