The 128-D 3-Way Corner Fitting is designed to create strong, clean 90° connections at corner points, allowing two horizontal rails and one vertical upright to meet in a single, rigid joint.

Commonly used where top rails meet corner uprights on level sites, this fitting forms the backbone of many structural frames—ensuring strength, alignment, and stability across multiple directions.

Manufactured from malleable iron, it delivers excellent load-bearing performance and long-term durability in outdoor environments. The integrated grub screw system secures each tube firmly in place, helping maintain structural integrity under repeated use.

This is a key component for building complete, stable frame systems, especially where multiple directions of load come together.
