If your bin throat is too damaged for one of our Lifetime Grain Bin Lids, you can use one of our BIN THROAT REPLACEMENTS. These replacement Bin Throats have the roof mounting flange included and are available in two sizes.
Lifetime Bin Throat Replacements make the throat opening 27" which will allow you to mount a Model L29 Lifetime Bin Lid on top or 32" which will allow you to mount a Model L34 Lifetime Bin Lid on top..
