Round Floor Latch

sturdy bike that will replace an old model, I haven't installed it yet

Unfortunately, this floor jack is absolutely useless. It is beautiful and valuable. The lifter is a cast part, which is unfortunately constructed the wrong way around. The side slope of the cast part points upwards (see pictures), which means that the part sits in the hole made for the lifter and only fits at the bottom, and at the top there is a wide gap tapered.
On top, on the visible side, you have to lubricate with kit or Sikaflex, which looks very ugly.
Furthermore, the part is -51mm in diameter and not 50mm as in the drawing.
Drills (Forstner drills) are available in 51mm only in non-dimensionally stable qualities, which then the hole
for the lifter also makes a less than good basis for this unfortunately not well thought-out lifter.

nice product but with rather uncomfortable use (edges too bright)
