Supplied equipment feet or cones ,etc?

I use cones also and after the same incident I drilled & tap the cones and bolted them down to the shelfs so the can't tip over anymore.

I also have little ones running about and I also have an Arc 100.2.which has an 8-32 screw holding the feet on.I bought four Audiopoint brass cones with an integral 8-32 screw to replace the rubber feet.Sonics are much better and the points grip enough to avoid slipping from child earthquakes ect.

Same as above for myself, except that I evolved to Mod Squad Soft Shoes, designed and manufactured by Steve McCormack when he was "The Mod Squad."

After all these years, even though my system is very high end now, I still prefer the Soft Shoes under most of my equipment.

They have won over all the spikes and cones that I have tried, and that includes most of the brands discussed here.
