Before
The new ones are chrome and match the other fixtures better. I also like their more modern shape.
After
They are the Siro Designs 3 3/4 Bright Chrome European Railing Bars from Lowe's.
I had a small problem installing them. Although the old and new pulls both measured 3 3/4 center-to-center, the new handles did not align perfectly with the previously drilled holes. To fix this, we took our power drill and a small drill bit and gently moved the drill bit around the top of the hole to make it a little larger. This allowed us to push the screw a little higher and line it up with the pull. If you run into a problem like this, just make sure that your new pull will still cover the hole if you need to make bigger.
Just a few more projects left in here!
