Wizz Pin or Solid stainless pin for control frame corner.  This is a cheaper alternative to a pip pin and considered by many as being more simple, straight forward and easier  to pre-flight check.

This pin fits 1 1/8" tube.  The standard size tube for speed bars or base bars.

If you are using larger diameter tube for a 1 1/4" heavy dual control frame or perhaps a microlight then you probably require the long version of this pin.
