The 3-Sided Glass Guillotine Fireplace Door is a remarkable design feat, measuring 6′ long and weighing 400 lbs. Engineered with a block-and-tackle pulley system, the door glides effortlessly into the wall above when open and offers an uninterrupted view of the fire through its three-sided glass design whe the door is down. Paired with a massive concrete hearth, it seamlessly combines function and elegance.
