External Coupling for 1-1/4"

The #70 Hollaender 1-1/4" External Coupling is a precision aluminum connector designed to join two sections of 1-1/4" OD pipe or Speed-Rail® in a straight, in-line configuration. Commonly used in lighting grids, grip rigs, and truss systems, this fitting creates a strong, smooth connection between pipes without the need for welding or special tools.

Manufactured from high-strength aluminum-magnesium alloy, the #70 External Coupling provides exceptional durability and corrosion resistance while remaining lightweight and easy to handle. Stainless-steel set screws deliver a tight, secure hold, ensuring a stable, non-slip joint that can be reused across multiple setups.
