Bolted 90° Fixed Clamp for Scaffolding & Structural Tube Connections
A Bolted 90° Fixed Clamp is a structural fitting used to securely connect two tubes, pipes, or scaffold members at a fixed right angle (90°). It is tightened using bolts to create a strong, rigid connection that prevents movement or rotation between joined components, making it ideal for stable structural assemblies.
Built for strength and reliability, this clamp is commonly used in professional scaffolding and industrial frameworks where secure fixed-angle connections are required. Its bolted design ensures long-term stability in both temporary and permanent installations.

Key Features

Creates a permanent or semi-permanent 90° fixed connection

Heavy-duty bolted design for maximum strength and stability

Helps maintain structural alignment and rigidity

Suitable for indoor and outdoor applications

Typically manufactured from galvanized steel, stainless steel, or malleable iron for corrosion resistance

Typical Applications

Scaffolding systems

Safety railings and guardrails

Tube-and-pipe framework structures

Industrial platforms

Handrail and barrier installations

Construction Features

Material options include galvanized steel, stainless steel, or malleable iron for durability and corrosion resistance

Fixed 90° geometry engineered for precise right-angle alignment

Bolted fastening system ensures a secure, vibration-resistant hold

Designed for structural load-bearing applications requiring rigidity

Weather-resistant finish suitable for indoor and outdoor environments

Why Use a Bolted 90° Fixed Clamp?

Provides a strong, non-rotating right-angle joint

Improves structural stability in scaffolding and pipe frameworks

Reduces movement and misalignment under load

Faster and more flexible than welded connections for temporary builds

Supports efficient on-site assembly and disassembly

Safety Recommendations

Fully tighten all bolts before use

Inspect regularly for cracks, corrosion, or bolt wear

Ensure correct tube size compatibility (Ø 1.625 / 1.9 in.)

Do not exceed designed load capacity

Follow OSHA, ANSI, and CSA safety standards

Recheck tightness during extended or high-load applications
