Review on 📏 Precision Magnetic Post Level Beams for Enhanced Leveling Efficiency by Jason Spainhour

Based on my experience of using this product for leveling and setting posts in the ground, I can only recommend this product as an aid when installing a few posts. It's often difficult these days to get these things from the store onto a rack so they're really flush with the page. Even with built-in tape. Especially if you are setting the post in concrete, it is highly recommended that you use a 3 or 4 foot level as a final step to fine tune the post just prior to pouring/backfilling. I would say this product is very useful up to this point. Again, if you really insist on just using these, suggest using an adjustable plastic or metal clamp to ensure the best flush possible.
