Riser screws prevent side to side workbenches
Your review: It is a sturdy shelf, but the old wooden shelves were better.
1. Use of wood screws that attached to the SIDE of the maple butcher block prevent placement of benches FLUSH side to side. This creates an annoying gap between benches which inevitably things fall into.
2. The metal shelf easily scratches compared to the wood top.
It would be better to have a WOOD TOP SHELF RISER for the wood top benches.
That said the shelf is sturdy (I did not install the partitions and middle shelf).
