If you check glider manufacturers weak link requirements as listed in the
respective POH's, you will find almost all are stronger than the maximum
lond permitted on a Schweizer tug hook. Overload a Schweizer hook and it
jams. To me, that says that all Schweizer tug hooks are dangerously
obsolete and should be replaced with Tost hooks - preferably with the tow
rope retract winch.

Our club is looking at new tow plane. The plane has a Schweizer tow
hook with "1200 lbs max" stamped on it.
Does anybody know what that relates to?
Is this the max gross weight of the glider or max tow tension or...?
I've tried Schweizer, but they couldn't help since they are no longer
making tow hooks.

Thanks for any insights.
