The SquareCable SPK Clamp is a compact aluminum mounting clamp designed to grip 1-3/8" to 1-1/2" (35-40mm) tubing commonly used with speaker stands, lighting stands, and compatible stage hardware. Its oversized wing knob provides fast, tool-free tightening, while the M8 mounting bolt provides a secure attachment point for compatible fixtures and accessories.
Built for mobile DJs, lighting technicians, production companies, venues, and installers, the SquareCable SPK Clamp provides a compact way to add a secure mounting point to compatible 35-40mm tubing. Its 1.2" (30mm) clamp width keeps the hardware compact while providing a firm grip for stage and event applications.
The clamp is manufactured from high-strength 6061-T6 aluminum with a black finish for a durable, stage-ready appearance. An integrated oversized wing knob makes tightening and repositioning quick without requiring separate tools, helping reduce setup and teardown time.
An M8 hex bolt provides mounting hardware for compatible fixtures and accessories, while the 165 lb (74.8 kg) Safe Working Load supports demanding production applications when properly installed. Its combination of compact size, tube compatibility, and tool-free operation makes it useful for speaker stands, lighting stands, staging systems, and other compatible 35-40mm mounting tubes.
