RAPid Risers™ are used under name-brand clamps to lift them into place. The mounting holes in RAPid Clamp Risers™ are able to fit a wide variety of brands and sizes: Wolverine, Carr Lane, REID, De-Sta-Co, Te-Co, All American, and Jergens. The CAD Drafter or Machine Designer simply looks for the clamp number on Rentapen’s RAPid Riser™ catalog page to get the corresponding RAPid Riser™ part number. RAPid Risers™ range from ½ inch tall to 4 inches tall. Rentapen accepts special requests for clamp risers that are taller or at a height not listed in Rentapen’s Catalog. Contact us today for a quote!
