1-5/8″ x 1-5/8″ Solid Strut Channel, 18″ – Pre-Galvanized
This 18-inch solid strut channel is made for stout, no-movement support in smaller builds. With a fully solid profile, it provides added stiffness compared to slotted channel when you need a firm, fixed connection. The pre-galvanized finish helps keep the steel protected in everyday jobsite conditions.
Notice: Because this channel is solid, attachment holes are not pre-made and should be drilled to match your layout.
