They worked on may QSC Subwoofer.

Good enough to modify and use on an elliptical trainer

Heavy duty and good looking. Installed on a 4 ft long storage bench that took 2 ppl to move. If I didnt have to make a trip to Home Depot to purchase washers my rating would have been a solid 5 star.

Just what I ordered. Received promptly.

well built nice looking very smooth operation great price locks work very well

Five sets of wheels are heavy. Package arrived in a USPS plastic carrier because the box was totally torn apart. Packaging should have been much heavier due to weight. Checked all of the wheels and found that every last one of the wheels had loose axle bolts, making the bearings very sloppy. Tightening the axle bolt with a 17 and 14 MM wrench solved that issue. The carrier bearings seam to be loose on all of them. Hopefully the ball bearings wont fall out. Even with all of those issues, I still gave the wheels a four. Materially, They feel well made, just the final QA process was not very good and Amazon totally blew it on packaging of the product.

These were used on a rolling storage unit that has multiple shelves to hold power tools. Works very well.

Arrived quickly and was exactly as listed.

Very sturdy wheels

Used on wine barrels
