8 PCS Strut Post Bases for 1-5/8 in Square Single Channel, U-Shape Floor Mount Post Base with 4 Slotted Holes, 5.7 x 5.7 in Flat Plate, Galvanized Carbon Steel Post Brackets
Channel Size Compatibility: Designed specifically for 1-5/8 in square single channel profiles; U-shaped opening aligns cleanly with standard strut dimensions, allowing vertical posts to seat correctly and maintain consistent channel-to-post positioning
Adjustable Anchor Layout: 5.7 x 5.7 in flat base plate increases ground contact on concrete or flat surfaces; four elongated slots allow anchor position adjustment during setup, supporting alignment correction without re-drilling or forcing placement
Static Load Reference: Each base supports up to 220 lbs under static load conditions; suitable for shelving frames, strut assemblies, and channel-based structures where vertical load transfers directly through the post into the base plate
Floor-Mount Installation Flow: Floor-mounted configuration for slabs or flat ground installations; post inserts into the U channel before anchoring; slotted holes allow leveling and squaring prior to final tightening, helping reduce cumulative positioning errors
Galvanized Steel Construction: Constructed from galvanized carbon steel for stable dimensions and consistent shape; surface finish supports indoor or outdoor utility environments and integrates cleanly with framing systems and general-purpose support assemblies
