Vertical opening batten ends as used by most other manufacturers.
There is a difference to the threaded length of those used by Moyes, so using other manufacturers may not allow correct sail tension adjustment. Select the type when ordering, Moyes for Moyes gliders, Wills Wing should fit all others.
This type of batten end often becomes worn in use and is then able to pop open in flight. If your glider uses this type of batten end you should check it is not possible to pop it open (the batten end should resist a vertical load of at least 6.5kg) and replace any that are worn.
