A telescoping mirror is a great tool for inspecting objects or areas that are obstructed from your direct line of sight. The telescoping mirror can be used to check for leaks behind a hot water heater, under a car for exhaust or oil leaks and even below floor boards for termite damage. The multi-flex, double ball joint neck allows you to adjust the mirror to any angle. This item features a 2 inch x 3 inch rectangular mirror made of shatter-resistant Lexan.
