The STEELMAN 41817 30-Inch Telescoping 2-Inch x 3.5-Inch Inspection Mirror is the ideal tool for when you need to look into tight and recessed areas. With the mirror unfolded the tool is a short 7-inches in length that can then extend out to 30-inches or anything in between. The double-ball articulated mirror is rectangular and measures 2-inches wide x 3.5-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, telescoping steel tool collapses and folds down to 7-inches in size and can be easily stowed away until it is once more needed.
