Power Tech plated piston rods and gland nuts resist scoring and corrosion. Heavy duty return spring (except for double-acting models) provides fast piston return & low collapsed height. Coupler on 10 thru 50 ton models is angled upward 5° for added clearance. Grooved piston top keeps load from sliding. Cylinders can be “dead-ended” at full capacity. Removable carrying handles on 100 ton and 250 ton models.
