We have a few not-so-rolling ladders from Tri-Arc (purchased via Grainger)
that we are using. These were originally the weight-actuated rolling type
but we found that while those worked reasonably well for a hefty fella like
me, they were uncomfortably unstable for our more petite lab members, so we
eventually removed the casters. They're still light enough, due to the
aluminum, for me to move around by hand even without the casters.
