 Poles exposed to wetting can decay when water remains in contact with
them or when rapid drying is restricted. Steel support sleeves
[Figure (l)] lacking base drain hole is a good example. Periodic retreat-
ment of such poles will significantly increase service life. Decay can typi-
cally be found where seasoning checks or bolt holes have exposed
untreated wood found beneath the treated shell.
