Just FYI,
There is a lightweight, 6 lb slide, that Engel makes and I am not really sure what the quality is like. It costs about $100.
The item I am selling weights about 25 lbs+ and is very stout. It does not rattle, has sealed bearings and is basically a lifetime unit.
Just in case there was any misconception, since I have already been lowballed via pm comparing this to the lightweight version.
Thanks for looking!
