Review on POWERTEC 17201 Double Swivel Caster by Christian Bar

Wheels with great grip! You need to trace the mounting plates. I used a Kason 61780500004 3-1/2"X3-1/2" with 1/2"-13 UNC threaded mounting plates and it worked great. A big advantage over swivel wheels is the ability to adjust the height of the wheel post installation the locks work great and if 2 of the 4 wheels are locked your carriage will not move great for my miter saw table I built.
