Innovative Research Labs, Inc.

Innovative Research Labs, Inc. was founded in 1996 by Brad Tupper MD, a practicing anesthesiologist and former electrical engineer, and Peter Miller, a former Microsoft lawyer with extensive experience in small company management. The company develops and manufactures products for niche markets, primarily in the medical marketplace. CASTrGARDs are used primarily in the operating room environment, but have application in varied other locations where wheeled carts run into objects on the floor which impede the movement of cart casters.

All company products are manufactured using recyclable materials in an AS 9100 compliant facility in Seattle, Washington USA. CASTrGARDs are highly functional and durable, with thousands of units in currently daily use. We welcome any dealer inquiries, both national and international.


Available in 3 sizes and 4 different colors, CASTrGARD can be conveniently ordered from dealers in the U.S. and around the world, or by filling out our online order form.
