GLASS DOOR KIT
Comes with everything you will need for the installation, including all brackets, screws, anchors, and insulation.
Many doors come in standard sizes, and larger distributors keep popular sizes in stock. Otherwise, you will need to order the door, which can take up to eight weeks.
Measure the size of your firebox opening, both horizontally and vertically. Make sure to measure in a couple of places and note the smallest measurement for each so the door will slide into the space. Also measure the width and height of your surround between any protruding parts of the mantel. A narrow surround may require a smaller door to accommodate the overlap at the firebox edge.

1. Attach lintel clamps to door

Stand the door on its bottom edge and either lean it against your leg as you work or have a helper hold it for you.

With a Phillips-head screwdriver, remove the four screws located on the back of the door where the floor brackets (bottom) and lintel clamps (top) will go. Set these aside; you will need them later to attach the brackets and clamps.

Assemble the two lintel clamps and attach them to the door at the top.
