Heavy wall black ground sleeve for 1 5/8 round posts. Requires driving anvil / drive cap tool (shown inserted into the ground sleeve in the first photo) to properly drive into the ground without damaging the ends.
Using a digging bar or ground sleeve auger to pilot a hole into the ground first is also recommended.
Our ground sleeves are heavily galvanized for in-ground longevity to match the life of our fence posts. Ground sleeves spend the entirety of their useful life in the ground and need the highest level of protection against corrosion. We then black gloss powder coat the sleeves.
They have a bottom opening for water to drain out with a post stop and 12" minimum reservoir. During cold weather months, this is important because water can turn to ice and expand. This will burst your sleeve and or move the post out of plumb.
These sleeves also include a black matching set screw. Once your post is inserted into the sleeve, tighten the screw to secure the post. This makes your post permanent or removable.
