MG-300 Impact Resistant Horizontal Rolling Window
The Mr Glass MG-300 horizontal slider window—also known as a horizontal roller—glides effortlessly along a precision track to deliver wide views and easy, one-hand ventilation. It's a favorite over kitchen sinks, along patios, and in bedrooms where a horizontal opening feels natural. A robust aluminum frame and laminated impact-resistant glass shield your home from hurricane-force winds, flying debris, and intrusion, while Low-E glazing keeps interiors cool and comfortable.
