I got this job for an office, they have dozens of file cabinets which are full, about 6' x 4' x 2', these are steel cabinets, full of paperwork files. Does anyone have experience in moving these? what tool do you use? I looked online and saw some sliders, not sure how effective they are against 900 lb cabinets, 10 reams per drawer, at 4 drawers, thats 40 reams, 20 lbs a ream, plus 100 lb steel cabinet. I also found something from bigslider.com, videos are great, not sure if I want to order from a 2012 website. And if I use sliders, I might be spending too much time on the move. Any links will be greatly appreciated.
