I own the HD9ST from BendPak. Also have the RJ-45, drip pans, aluminum ramps, and castors. I love everything about my lift and it has performed flawlessly. Thank goodness, it's so rare that I find myself in the minority ;)
I think the BendPak specs assume the front of the rail (high point of the garage floor) is flat against the baseplate, which could be tricky because it can be adjusted otherwise at installation. So the distance between floor and rail could vary on the first lock, but normalizes from lock #2...
More likely I'm missing something. Still focused on the fact that the thickness of the welded cross-member is important to you. I'm not as consumed by this as you are, just trying to help if I can. Probably pissed a lot of people off with those giant pics, but I'm not a tech guru.
I think the HD-9 is not going to work for you. The following pictures should demonstrate why. As I mentioned above, the lift is level, so if your garage is sloped, there will be more gap when the lift is in the down position, between the rails and the garage floor at the downside of the slope...
The locks safely release consistently at 1 9/16 inches. This means I tested about a dozen times, trial and error, and without fail when I could raise the lift off the locks by one and nine-sixteenths inches (or more of course), I could release all for locks and lower the ladder.
I will do this. At the office now, but should have it within a few hours. Mine is the ST version, but other than the dimensions I am relatively certain all components are the same.
sounds like a trick question. If the ladder is beneath the lowest set of locks, it doesn't.
Provided all locks are level (most garages have some slope so the distance from ceiling to floor is different in the front versus the back of the garage), you need to raise it an inch or two to get the...
I have a nice Mirabelle in my garage utility sink that takes a threaded adapter, so I could use my hose/hot water. Mine is a pull-down spray faucet.
Bad idea, I promise.
Stick with a single faucet with threaded spout, no pull-down hardware.
Also, if you don't plan to bolt your lift to the floor, buy the casters. Your lift will creep on you over time and you will need the casters to reposition it.

I made the mistake of storing a gallon of acid under the sink in my garage. This was a pretty expensive ceramic coated cast iron sink. By the time I discovered the mess, there was an unbelievable, INCREDIBLY unbelievable amount of rust buidup on any metal exposed under the sink, ESPECIALLY the...
