Product review (5 stars): Add new life to your old dryer!
The felt seal fits perfectly.  I found that using a handful of spring clamps to hold it in place as I stretched it on the drum worked very well.  I didn't read the directions closely so don't remember if they tell you this, but if you have the drum sitting on the floor with the felt seal end facing up, when you squeeze the glue under the felt seal, the glue will run down and out from under the seal and into the channel that rides on the rollers.  It's better to have the drum on its side when you apply the glue so it doesn't run out as much.
