The easy slip-on baseboard heater cover that instantly rejuvenates old, yet perfectly functional, baseboard heaters. Baseboarders Inside Corners are designed to cover the gap produced when 2 Baseboarders panels meet in an "L" configuration. Consistent with all Baseboarders accessories, the Inside Corner just slips over 2 Baseboarders panels to maintain the consistent clean aesthetic from one end to the other, even around corners.
