Slotted Square Pre-Aged Copper Rain Chain – High-Flow 5/5 Cups
Slotted Square Cups #3121-AC – Pre-Aged Pure Copper
A distinctive square-cup rain chain with architectural slotted cutouts and a naturally torch-aged finish. Each medium-size cup is individually welded by hand from pure copper, with a folded upper lip for added stiffness and durability.
The pre-aged coloration is created by heat from the torch rather than paint or a chemical coating, giving every chain its own variations in red, brown and dark copper tones. The result is a handcrafted piece that arrives with the character of weathered copper from day one.
With a 5/5 Waterflow Index and a generous 1 5/8-inch bottom opening, this design is built to handle heavy rainfall and is an especially practical choice for Hawaiʻi homes.
