These are really neat bean pole trellises designed for us by a machinist friend. Get a piece of 1/2" electrical conduit, insert the topper into the conduit, drive the other side of the conduit into the ground, tie strings down from the topper to the ground, and tie the strings to the ground with ground stakes. Voila! Instant trellis, perfect for many climbing vegetables or plants. Even better, there's tremendous flexibility in height, as you can make the conduit any length you want. Perfect for beans, cucumbers, morning glories, or any other climbing plant that climbs a pole or string.
DOES NOT INCLUDE CONDUIT, STRING OR GROUND STAKES.
We recommend taking the trellis topper with you to the hardware store when you buy the conduit. We have found that some imported conduit does not have very good quality control, and the 1/2" diameter is off by just enough that the topper is not a snug fit.
