I did not sell such a thing to the home center, I was really saved here. Although it was attached to a boggy carriage, it was possible to securely park even where it became a slope, and it became possible to work safely. I think that it is an essential item for dolly.
Because the studio is narrow, the stand of the tool is mobile. Since it was fixed at 2 adjusters at the time of using the tool, there is a possibility of moving during use, too, purchasing this nonsync lock to avoid the danger, although not much has passed yet, but at the present time, It is also good that the pedals for locking and releasing are separate. I am satisfied. We are planning to use another one, as we are in the process of manufacturing a mobile tool rack.
