List Price: $2.10 Sale Price: $1.75
The 1099-9 thumbnut is a screw that secures the trough cover to the distributor trough. The cover shields the distributor trough, which disperses water onto the humidifier pad. If the trough cover needs to be replaced, it is a good idea to also replace the thumbnuts. This part fits models 747, 747L, 1099, 1099L, 1099LH, 1040, 1040L, 1040LH, 709, 709L, 709LH, 1040R, 1099R, 709R, 1042, 1042R, 1042L, 1042LH, 1137R, 1137, 1042DM, 1042DME.

thumbnut review by Byron Kuxhaus (Royal Oak MI US)
Assume 5 is the highest. Surprised they came packaged individually. Bought them for spares for future use when I lose one!
