Safety in the lab starts with a protective shield or debris shield. The shield consisting of a fixed side and a hinged door side can be custom designed to fit any and all testers made by Instron™, MTS™, Thwing Albert™, Zwick™, Tinius Olsen™ and others. It places a protective shield between the operator and the breaking test specimen. The shield is constructed of shatterproof clear polycarbonate surrounded by aluminum framing. The door is fitted with a latch that can be configured with an interlock to help protect the user from moving parts on the test frame.
