It’s darn near impossible to hold a 16 or 18-foot strut level on the door with one hand and use a drill with a TEK screw, on the other hand, to screw through 20 Ga. steel and expect the strut to be level and centered on the door.
One of our strut connector kit’s excellent features is, we provide starter holes at the center of each connector, making it much easier for one person to install the strut, starting in the middle of a door with a pre-drilled hole.
Note: When assembling the two struts to the connector. It’s more critical where each end of the strut lines up with each side of your doors end brackets. Struts are 7′-11″ not 8′, so you may have a 2-inch gap in some cases in the middle of the strut.
Assemble you strut connector kit is on level surface. The garage floor will most likely be your best option. Line up ½ of the strut connector “ parallel “ to the last 18 in. of the strut and use a marker to mark where the connector begins inside the strut. Repeat for the other end of the connector
Using the 1/2″ TEK screws included in your order secure the strut to the strut connector as shown in the photo. Keep 1/2 inch away from edge of the connector when inserting screws. Repeat on reverse side
