You asked for a thicker zen loop chain than our copper version. This is much thicker, each link hand cast in aluminum, then powder coated satin black or bronze.
The vertical bars help water flow downward.  Links are shipped individually and are easy to assemble using our patented "Wedge Gap"™ design.
 
Size: 3 1/8" Diameter x 3/8" Thick
 
Recommended accessory:  Installation Kit Black or Bronze
 
This product ships in 3-4 weeks.
 
Please note: Link Style Rain Chains do not contain all the rain water as well as the cup styles and may result in water splashing. Do not use in an area where the splash could cause potential water damage to a wall or structure.
