Just like the handles you'd find on most toolboxes, these are formed nickel-plated steel handles with screw-on staples.
The small handle is about 7 1/4" long overall when installed, and has 1 1/2" wide staples. The large handle is about 8" long and has 1 5/8" wide staples.
Size given is the approximate handle diameter. Requires #8 screws (not included).
