18inch 450mm Aluminium Alloy Miter Bar Slider Table Saw Gauge Rod Durable in Use

The overall quality was excellent. As mentioned by another, it took a little while to come. Included: the basic bar with 3 black "washers" attached, 3 extra black washers, and two metal "discs", one at each end. The basic bar fit perfectly in my 3/4 inch Craftsman table saw slot. But, the two metal "discs" stick out from the side of the bar. Clearly, you cannot use the bar in a 3/4 inch slot with the metal discs attached. So, what were they for?What were the extra black washers for? I was even initially confused as to which side was up! I was able to find a short video on the internet showing how to adjust the black washers for a good slot fit. Basically, the washers are "split". Tightening them forces them to expand into the slot. So, I guess the 3 extra washers are just "spares". One would then think that the "black washer side" is up. But, on the opposite side, there are several countersunk holes. I'm just guessing that the idea is that one could install the bar up or down depending upon their application.Now, for the metal washers on the end. I found a "similar" slide at Inca with "similar" metal plates on the ends. It was stated that these were for "t-slot" applications. Using the metal washers in a t-slot would seem to decrease the precision of the fit. But, maybe that's okay for some applications.

Very well made, definitely will be making sled with these. Was packaged very well, coming from Shanghai to U.S. Ga took exactly 14 days, not bad considering the quality and price.

As others have said, these are really nice quality. They fit my Rigid table saw tracks perfectly and I really like the black adjustment washers to ensure a tight fit

Precision is good, making it sturdy.I bought it and was right.

Looked for miter bars for the table saw sled and decided to order these. Could not be more satisfied. Made of high quality aluminum alloy with perfectly center eyelets for attachment. Took over a month to receive but is due to shipment from China. I'm very satisfied with the purchase.
