Ask the Experts | Ask the Door Guys | Need Doors Prepped for I-Beam Cut-Out


I have a pair of doors with an I-Beam coming through the top. Can I order doors prepped for this?



Yes, this is known as a Monorail Prep. There are three different size standard factory preps, as well as a custom prep available. In addition to the notch in the door, it also comes with a neoprene seal that will need to be cut in the field to match the beam. Give us a call and we will guide you in collecting all the proper information for doors prepped for I-Beam cut-out.
