Another suggestion - please don't use your bare fingers when
along the cable. Wear leather gloves (or equivalent) - you'll still feel
broken/frayed wire but just without the blood that may accompany

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

|[DCHAS-L] Hood Sash
We are looking for some ideas on hood sash
inspect all our hood sash cables quarterly by a visually inspecting
and running a finger along the cable to feel for any bumps or frayed
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
twist and it is not visible without a magnifying glass, and if it were
away while someone was in the hood, we would have a serious injury.
are thinking about instituting a change schedule for all the cables.
anyone have any ideas or comments?
information on cable breakage, or has anyone heard of an incident of
cables breaking at the same time causing the sash to completely fall?
Does anyone have a policy they would be willing to
