FYI
When you purchase a one-piece strut, there are pre-drilled holes in the brace that line up with each vertical style on the door. With the strut kit, the pre-drilled holes may only line up in the center and ends. It’s our # 1 biggest complaint “the holes don’t line up.” The truth is, you get a more secure bond with the strut and door when you use the TEK screws to drill the hole and attach it to the vertical style. The screws help straighten the door panel by pulling it tight against the strut.
Insulated Door Owners
Struts are attached to the vertical styles on steel doors. However, not all insulated doors have styles built in the door. If your not sure, tap a small finish nail through the skin under a hinge. If it’s hollow you will need to attach the strut to the hinges.
