## Questions & Answers

**Q: where does this item ship from?**
A: If it comes from us, it's shipping from Kansas City, Missouri!

**Q: will these rollers work on Jeld-Wen vinyl sliding patio doors?**
A: There are many different profiles used for patio doors. Try to find the spec. drawings of the door and compare it with the drawings of the rollers to see if it fits.
Also possible is that the manufacturer of the door can help you with your choice. Sure thing is that the tandem rollers are far better than the single ones.

**Q: how to install D-1791 roller assembly**
A: First you turn the adjusting screw so the wheels retract all the way in the door. Now you lift the door up and out of track, get help it is heavy. Turn the adjusting screw so the wheels are as far out as possible so you have something to grab onto to pull out assembly. There is a screw that holds the roller in place just above the adjustment screw. Remove this screw and pull roller out. Reverse to install new roller. After you put door in place adjust so the door slides easy. When the door is out is a great time to clean the track. On my door there is no metal piece to remove as with Matt S.

**Q: I'm looking for a Disco screen door roller number 1189 or a D 1830**
A: Please review item D 1830 that is available.
