This hose clamp extends from half an inch to an inch in diameter. It is made entirely of metal and is intended for use with Maytag brand washing machines.
It just snaps back in but it was a very tight fit and took two people to force it in. Plus I had no instructions and hadn't seen it before it broke so it took a little time to figure out where it was supposed to go. The arm doesn't connected to anything except the rack. I guess water just shoots up into it from below.
The dishrack came in one box I opened the box snapped on the rollers and the bumpers and put it in the dishwasher, could not have been easier Thank you partselect
