No physical protection to too easily breaking the exposed glass bottles

I intend drilling to half depth, holes in the cab either side. Then some
steel studding of length of the internal cab width plus one hole depth.
Some silicone sleeve over that (could be heatshrink tube) , just to
disguise the threading, then a nut on either end. When in place , wind
out the nuts , to engage with the cab, then some nail varnish as threadlock.
Any other ideas I might consider?
