Will this fit my garage door?

It is sized for doors about 8 feet wide, with a 147-inch length. Check your door's width and whether the panel has pre-drilled holes for a strut before ordering.

One galvanized steel U-bar strut. Mounting hardware is often not included, so plan on buying self-tapping screws or bolts sized for your door's panels.

Do I need one strut or two?

One strut across the top panel is common on 8 ft doors. Doors that sag or carry a heavy opener often use a second strut lower down.

Will it work with my garage door opener?

Yes, but the added weight can require a spring or opener force adjustment. Have the door balanced after installing it.

Is $48.99 a good price?

It is the only new price listed as of November 7, 2026, at Amazon, so there is no competing new price to compare against. Used or aftermarket struts sometimes sell for less.

Our take on the Wayne Dalton Garage Door Reinforcement Strut, 8 ft

This is a galvanized steel U-bar strut made by Wayne Dalton to stiffen an 8-foot-wide garage door. It spans 147 inches and bolts across the door's horizontal panels to reduce flex and sag. It is a single-purpose hardware part, not a full reinforcement kit, and at $48.99 at Amazon as of November 7, 2026 it is the only new price listed.
