STRONGARM® Vertica™ Arms allow any size operator, short or tall, to comfortably use a plant floor operator interface. Squeezing the grab handle makes the interface weightless and able to be repositioned. The Vertica's unique gas spring counterbalancing system automatically locks in the desired vertical position. Swivel at both ends is standard. Ideal for flat panel interfaces, the Vertica arm can counterbalance up to 100 pounds. Available in NEMA 4 (cast aluminum) and 4X (stainless steel), the Vertica can be attached to any horizontal or vertical surface or 3.5 inch OD pipe.
