steth ‘n go – The True Magnetic Stethoscope Holder – Built to Last. Magnetic-Mechanical Technology. There is NO LEATHER & NO VELCRO in this product. It contains two pieces: (1) hip clip (2) steel tube clip. The magnet is located ONLY within the hip clip. The hip clip is made of a durable, flexible plastic material that can be placed over a belt or a waistband. The tube clip contains a steel piece that is screwed onto a plastic tube clip. The steel is galvanized to prevent it from rusting. Another clip area is meant for snapping one of the ear tips into it. The tube clip needs to be placed at the end of a stethoscope near the diaphragm. The tube clip will pinch large stethoscope tube sizes (e.g. Littmann Cardiology 4, Master Littmann Cardiology) but will not damage or interfere with its function.
