Review on 🔧 Premium Phenolic Zero Clearance Insert: Compatible with Delta Uni-Saw Contractor, Large Grizzly, and Other Table Saws - 13-3/8” x 3-3/4” x 1/2” Throat Plate Opening by Jerardo Phi

The material in this product is incredibly durable. It's a kind of super-dense, durable plastic. It's not lightweight fluffy cheap plastic. My current insert on my old grizzly saw is made out of lightweight, low quality plastic. This insert is built like a tank and light twice as dense and heavy. There's no room for a riving knife in it, so if you're upgrading the riving knife on your old saw that didn't come with it, or if you want to use the original riving knife, you might just need to cut a slot in it for the riving knife to go through, what so simple would be like drilling a few small holes and using a jigsaw.
