Fitvids monolift attachment

These monolift arms are spring-loaded rather than using the counter-weight system more common among monolift attachments. As such, they take up a smaller footprint. I have a custom fabricated rack that is too shallow for Titan's monolift arms, for example, but these fit comfortably inside. There is a catch to using the spring-loaded version, however. Until the weights get heavy enough for the springs to fully uncoil (around 135 lbs or so), you'll have to apply downward pressure into the arms to extend them fully to get the "snap back" effect upon unracking. Once this point is kept in mind, the monolift works great. Now I can bench inside my rack and unrack heavy weight by myself without aggravating my old-man shoulders! Perhaps my biggest complaint about its build quality is that there is no way to lock it in securely to your rack (e.g. via hitch pin). Only thing holding it in place is the weight of the attachment, combined with the load on its arms. Also, the back side of the attachment, the side that anchors it to the rack, only extends about 2/3 of the way across the 3 inch tubing (see attached pic). The attachment is advertised as being for a 3" x 3" rack, but it seems better suited for the odd 3" x 2" rack. Maybe these are issues they can address in future versions of this monolift attachment? (This, combined with the previous point, made me wary enough that I secured the attachment using Gorilla tape, which is not a problem for me because I don't plan on removing the attachment once it's set up.)
