Scientific Instruments, Inc.

Since 1973, SDI has been a leader and innovator in the field of manufacturing products from recycled tire rubber. At our facility in Eugene, Oregon we mold our full product line of traffic safety, parking lot safety, and wheel chocks using both buffings and crumb rubber. At our plant in Elkhart, Indiana we use crumb rubber to produce bases that sell by the truckload, thereby saving on freight cost to our mid-west and eastern customers.
SDI's products are environmentally conscious and will meet your traffic and safety needs. Contact us for high quality and excellent service.
