This piece came exactly as I needed it to. Polished and with precise measurements. I measured every aspect and it is perfect down to the thousandth of an inch.

Was a little concerned with shipping. Considering this is kinda fragile.I was very pleased to see item was shipped with extra care. It probably took a good 10 minites just to unpack. But it was worth it, because item was in perfect condition. NOT a ding, dent, ot scratch. They even put styrofoam inside. To mantain its sqaureness and structural integrity.YES, I would buy from them again and I highly reccomend.

Every thing is as ordered. I’m using this to build a riser to mount a Scotty pot puller.
