As the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3.5K # 23-468-469 are a standard size for a 3,500 pound axle, they should fit your 2002 Featherlite 3110 without issue.

In order to confirm fit of the Bearing Buddy Bearing Protectors you need to measure the bore of the hub, I can't confirm this for any one particular trailer. I have attached a full list of our selection but the part # BB1980A-SS fits a 1.980" hub bore. The measurements need to be taken to the nearest thousandth of an inch. view full answer...

The face plate of the lock is 5-7/8" wide x 5-1/2" tall so it will easily cover the cutout hole. view full answer...
