This pair of tape measures has magnetic tips at the ends of the tape measure to hold it in place against another magnetic item. For example, I placed the end against my refrigerator and it stayed out as I measured some distance from the refrigerator to the opposite wall. Heavy duty and well made. Pretty heavy feel. Wire belt clip on the back but it is small and very tight. Not easy to work if you have big fingers. When tape measure is extended, the tape can be locked in place by using the switch at the front of the tape measure (pushing it up). Push it down and the tape quickly retracts. Watch your fingers. You can also hold the tape extended without locking it by pressing the blue button on the buttom of the tape measure. Tape will remain extended as long as that button is pressed. Release your hold on the button slowly...Slow release to retract the tape measure bit by bit. Highly recommend for every household and every handyman/woman. Thank you Walmart Spark Reviewer program for allowing me to try this product.
