Multiwing uniboss center boss for an SH QD bushing, extended 62 mm length, pull-through style (Wing Fan calls this reverse mount). It has a 75 mm pilot that fits a fan hub bored to 75 mm, bolts in with 5 bolts, and clamps to your shaft with an SH bushing. The bushing is not included.

• 75 mm pilot, fits hubs bored 75 mm (same 5-bolt hubs as our P1 center bosses)
• Extended 62 mm length
• Pull-through (reverse mount), BR style
• Takes an SH QD bushing (sold separately)

The last photo shows the boss installed in a 9-blade hub as an example application. The hub is not included.

Need a P1 taper boss instead? See the AS/BS and AR/BR 5-bolt bosses. Multiwing and Wing Fan bosses are interchangeable.
