The KPC-048 Pipe Clamp Base Flange (alternate profile) is a bolt-on malleable iron fitting for 42.4 mm OD, 1-1/4" Sch. 40 pipe. It terminates a pipe to a flat surface with bolt-down mounting in an alternate base flange profile, using stainless steel hex screws to lock the pipe without welding so frame, rail, and display structures can be assembled and revised on site.
Why It Matters
Base conditions vary from job to job. This alternate flange gives installers another bolt-down profile for pipe terminations while keeping the same 42.4 mm outside diameter pipe clamp fit.
Key Features
Alternate bolt-down flange profile terminates pipe to flat surfaces for uprights and frame starts.
Malleable iron casting per ASTM A197 provides a durable body for tubular structures.
ASTM A153 hot dip galvanized treatment plus zinc plating supports corrosion resistance for demanding environments.
Stainless steel hex screws lock the pipe firmly without welding, helping crews build and rework faster.
Applications
Used for posts, upright frame starts, display bases, platform details, wall-adjacent structures, and pipe systems where this flange profile fits the mounting condition better than the standard base.
Compatibility
Fits 42.4 mm OD, 1-1/4" Sch. 40 pipe; related sister fittings cover the alternate KUPO pipe clamp diameter.
Frequently Asked Questions
Does this fitting require welding?
No. It locks the pipe with stainless steel hex screws, so the structure remains bolt-on and easier to reconfigure.
Why choose the alternate base flange?
Choose it when the mounting surface, bolt pattern, or profile preference suits this alternate flange better than the standard base flange.
What pipe size does this version fit?
This version fits 42.4 mm OD, 1-1/4" Sch. 40 pipe, commonly used as 1-1/4" nominal Schedule 40 pipe.
