Sleeve

The 149-D Straight Coupler Fitting is designed to join two tubes of the same size in a straight line, creating a strong and seamless extension.

Ideal for extending rails, uprights, or custom builds, this fitting ensures proper alignment while maintaining structural integrity across the connection point.

Manufactured from malleable iron, it offers excellent durability and load performance, making it suitable for both residential and commercial applications. The dual grub screw system provides a tight, secure fit, helping prevent movement and maintaining a rigid connection over time.

Whether you're increasing span, repairing a section, or modifying a system, this fitting delivers a clean, professional result.
