The MORRIS PRODUCTS 17454 is a four-hole square post base channel designed to anchor 1-5/8 inch strut assemblies to floors and other flat surfaces. Constructed from galvanized steel, it provides corrosion resistance suited for both indoor and outdoor installations. The side orientation configuration positions the strut horizontally relative to the base plate, simplifying alignment during rough-in work. The base measures 6 inches by 6 inches and accepts four fasteners for a secure, low-profile mount. Electricians and general contractors reach for this fitting when transitioning strut runs from vertical drops to floor-level terminations or equipment pads.
This post base channel is appropriate for residential and commercial electrical installations where 1-5/8 inch strut channel systems are used to support conduit, cable tray, mechanical equipment, or panel bracing. Typical applications include securing vertical strut posts to concrete slabs, equipment room floors, or structural decking. The four-hole pattern distributes load evenly across the base plate, making it a reliable choice for heavier support assemblies where a single anchor point would be inadequate.
Key Features
Sized for 1-5/8 inch strut channel - standard fit for common unistrut-style systems
Four mounting holes for even load distribution and positive attachment
Side orientation simplifies horizontal strut alignment at floor level
6 inch by 6 inch base plate provides a stable, broad footprint
Galvanized steel construction resists corrosion in typical interior and light exterior environments
Single-pack quantity for project-specific procurement
Compatibility
Designed as an OEM-style replacement and new-installation fitting for 1-5/8 inch strut channel systems used in residential and commercial electrical and mechanical support applications.
Installation Notes
Installation is typically performed by licensed electricians or general contractors following applicable NEC and local building code requirements for support structures. Fasten the base plate to the mounting surface using hardware appropriate for the substrate - concrete anchors for slab applications, structural bolts for steel decking. Verify the surface is level before securing the plate to prevent racking of the strut assembly. De-energize any adjacent electrical equipment before working in the immediate area.
