This tool doubles as a telescoping magnetic pick-up tool and an inspection mirror. Attach the mirror housing to the magnet and you have a 2 1/4" diameter inspection mirror. Remove the mirror, and you have a magnetic pick-up tool which extends from 7 3/4" to 21 1/4". Powerful magnet holds 2 lbs. Locking teeth prevent the mirror from swiveling on the magnet. Also, the non-rotating telescopic handle firmly holds the mirror/magnet in position when extended.
