It would be a good idea to check with your hood manufacturer. Depending on
the age, most hoods made in the last 10-15 years (sometimes older) were
designed with braking or fail-safe mechanisms that will prevent the
"guillotine-effect" in the event of a cable break. The manufacturer should
be able to tell you if your hoods have this safety feature.
Also, I have seen that when the pulleys are made of plastic (e.g. nylon,
etc.) they can grip the cable and cause it to unwind and rewind as it
passes over the pulley, which speeds up wear. It may be a good idea to
consider replacing plastic pulleys with steel pulleys.

[DCHAS-L] Hood Sash Cables
We are looking for some ideas on hood sash cables:
We inspect all our hood sash cables quarterly by a visually inspecting the
cable and running a finger along the cable to feel for any bumps or frayed
wire. We use 3/32? stainless steel ?aircraft grade? cables with a rating
of 900 pounds. We have found wire that has frayed in the middle of the
twist and it is not visible without a magnifying glass, and if it were to
give away while someone was in the hood, we would have a serious injury.
We are thinking about instituting a change schedule for all the cables.
Does anyone have any ideas or comments?
Does anyone have any information on cable breakage, or has anyone heard of
an incident of both sash cables breaking at the same time causing the sash
to completely fall?
Does anyone have a policy they would be willing to share?
