Extends an adjustable Pylex screw to 24 more inches, to push it further into the ground. Its steel structure gives it the same resistance and durability as the Pylex foundation screws. A good solution in case of major freezing or insertion near foundations. Easy installation: Just insert the extension between the head and the rod of the adjustable screw. Baked powder coating finish provides excellent rust resistance. Is compatible with Pylex 32 in or adjustable Pylex screws 50 in. Offers long term protection since the wooden post is above ground level.
