A center rail is a horizontal rail crossing the center front of the door for stability.
We recommend center rails on all doors over 50” for stability to prevent warping or twisting. If you choose not to add a center rail to any doors over 50” there will not be any guarantee against warping or twisting.
We cannot guarantee any door over 60", even if it has a center rail.
To request a center rail, you will need to specify in the Additional Instructions section on the last page of checkout.
We can do custom placement of more than 1 Center Rail for an additional charge.
