This end cap adds a finished touch to the end of steel or wood closet rods. They have a 1-3/8" inside diameter so they work well with a 1-3/8" or 1-5/16" diameter rod. End caps will not work with 1-1/4" rod. They come with a 10-32 set screw and hex wrench for fastening to the closet rod. Sold as singles. Designed and fabricated by ARMdesigns.
1-5/8" outside dimension.
1-3/8" inside dimension.
3/4" wide.

The silver color is from the finish grinding after welding. Material is raw steel and are unfinished (no coating) and will rust over time.
In the the listing photos I am using 1" black iron pipe, it has a outside dimension of 1-5/16" and makes a sturdy inexpensive closet rod. Black pipe can be found at home improvement stores.
