It swivels while the gate is moving, and adjusts to the ground due to the spring. It is lockable by using the brake. Installation was a bit tricky in that my gate is about 6 feet long and goes up an incline.

The homhoo caster is a great solution for sagging gate. The assembly has an appropriate amount of heft and appears to be made of a decent gage metal. It's very solidly built.

The mechanics look strong and the mechanism is definitely hold quite of bit of our gate’s weight. The spring seems to be of good quality and appropriate tension for a setup like this.

The wheels are sturdy and the lock is great and the miter saw does not move. And the brake pedals are metal which is rare enough in general, much less at this price point. Used them for my portable home work bench with built in saw.

The wheels are easy to install and include everything needed to install with two options for either wood screws or nuts and bolts. Included bolt and nut as well as wood screw hardware.

These are much sturdier than i imagined they would be. They lock and unlock easily too! Just about all my heavy equipment is on casters with top mounted locks so i can move it for cleaning or repositioning for a specific project.

The brake drags against the wheel on 3 out of 4 casters. They are made with cheap parts and are below average at best.
