The KPC-148B Pipe Clamp Base Flange (alternate profile) is a 100-series bolt-on fitting for 48.3 mm OD, 1-1/2" Sch. 40 pipe. It terminates pipe to a flat surface with bolt-down mounting in an alternate base profile, using stainless steel hex screws to lock the pipe without welding so smaller-format rail, display, and frame structures can be assembled and reworked on site.
Why It Matters
The black finish helps visible pipe structures sit quieter in scenic, retail, and event environments while keeping the same no-weld pipe clamp workflow.
Key Features
Alternate bolt-down flange profile terminates 48.3 mm outside diameter pipe to flat mounting surfaces.
Malleable iron casting per ASTM A197 provides a durable body for modular tubular structures.
ASTM A153 hot dip galvanized treatment plus zinc plating supports corrosion resistance in demanding environments.
Stainless steel hex screws lock the pipe without welding, helping crews assemble and revise frames cleanly.
Applications
Use for upright posts, display bases, platform details, wall-adjacent structures, fabricated bases, and pipe systems where this profile suits the mounting surface better.
Compatibility
Fits 48.3 mm OD, 1-1/2" Sch. 40 pipe; related sister fittings cover the alternate KUPO pipe clamp diameter.
Frequently Asked Questions
Does this fitting need welding?
