These wheels are big, strong and extremely well made. Brakes hold securely in place. Worked great for a mobile work cart. Harbor freight cart.

They roll smooth, lock down tight and don't budge. They swivel and roll with absolute ease. I have to unlock them by hand, which isn't a big deal, but it would be nice to be able to do it with my foot.

The bolts, lock washers and nuts are sturdy. Definitely heavy duty and came with screws and screwdriver. They are so strong and sturdy.

Whatever bearing they used for the plate feels crunchy. Didn't hold up.

Caster wheels roll perfectly on my cement patio. Locking wheels make it stationary when needed, mobile when necessary. Only one issue is the screws. There are a lot of screws if you want them secured well.

Put these little casters on a small nightstand. They're quite sturdy and well built. Sturdy, inexpensive and low profile.

Easy to install, sturdy and lockable, too. Buen material aun no las utilizo pero se miran buena calidad.

Says it's a 1 but the plate dimensions are 1.
