This is a genuine Lippert OEM hat-profile structural extrusion used throughout RV construction and repair. Hat channel sections like this one appear in floor framing, wall stud assemblies, slideout structural decks, and underbelly support systems. If you are matching an existing section during a structural repair or restoration, this part number ensures you get the correct profile dimensions and material spec directly from Lippert.
Hat channel -- named for its top-hat cross-sectional shape -- is one of the most common structural extrusion profiles in RV manufacturing. Lippert uses hat channel throughout their slideout systems, floor decks, and chassis sub-framing on a wide range of travel trailers, fifth wheels, and motorhome chassis. The raised crown and flanged feet distribute load across the mounting surface while keeping the profile lightweight.
Part number 106059 specifies an exact profile: 1.5 inches wide at the crown, 1.5 inches tall, with a 0.543-inch flange width and a 1.053-inch overall base dimension. Ordering by part number rather than nominal size ensures your replacement section matches the existing assembly without shimming or modification.
Crown, flange, and base dimensions match the factory Lippert specification for direct replacement without modification.
Used in floor framing, slideout deck structure, underbelly support rails, and wall sub-framing across many Lippert-built coaches.
Top-hat cross section provides a high strength-to-weight ratio and a flat mounting flange on both sides for secure fastening.
Sourced directly through Lippert Components, ensuring material grade and dimensional tolerance match the original factory installation.
Hat channel gets its name from its profile: a raised rectangular crown flanked by two outward-facing flanges, resembling a top hat in cross section. In RV construction this shape is used wherever a structural member needs to span between support points while offering a flat fastening surface on each side. Common locations include:
Hat channel comes in many profiles, and even small dimensional differences can prevent a flush fit or require shimming that compromises structural integrity. Verify all four key dimensions before ordering: crown width, overall height, flange width, and base width. For part 106059 those are 1.5", 1.5", 0.543", and 1.053" respectively. If your existing section has a Lippert part number stamped or labeled, that number is the fastest way to confirm a match.
Lippert Components supplies OEM structural hardware to a large share of North American RV manufacturers, including many Forest River, Keystone, Coachmen, Grand Design, Jayco, and Thor-built coaches. If your RV was built on a Lippert chassis or uses a Lippert slideout mechanism, there is a strong likelihood the structural extrusions in your floor and slideout assembly were sourced from Lippert and are spec-compatible with this part family.
