Review: Good product that fits perfect. - Exactly as it says and I would buy it again. Quality product for the money.
Review: Fulfill the need of lattice repair - Purchased to repair lattice work on the front porch, the lattice work and rest it off instead of having to weld it up. I was able to use these parts to install with a short new piece of iron and new feet. The set screws allowed me to position and lock them in place to secure them. I did put some Apoxsee around the base of the foot to hold everything in place but these work very well and made it a very inexpensive repair for some very expensive lattice work
