The STEELMAN 41816 21-Inch Telescoping 1-Inch x 2-Inch Inspection Mirror is the ideal tool for when you need to look into tight and recessed areas. With the mirror unfolded, the smooth, slim handle extends from 7.75-inches to over 21-inches, and the included pocket clip is perfect for keeping it close by. The double-ball articulated mirror is rectangular with rounded corners and measures 1-inch wide x 2-inches long and can swivel 360 degrees to allow you to look at any angle. This enables you to easily perform inspections on HVAC systems, automotive engine compartments and undercarriages, not to mention using it around the house to find things under beds, behind bookcases, and other hard-to-see places. When done this durable, zinc-plated brass tool collapses back down to 5-inches in size and the handy pocket clip lets you stow it safely until it is once more needed.
