Te OR-2800 will fit in just about any tower, including a Tri-Ex W-51 which has
a 9" top section. You have to remove the mast clamp and rotate the rotor so it
goes in between the cross bracing. You can the orientate the holes so the 3
side of the rotor line up with the edges of the rotor plate. Then you can
mount the mast clamps, what ever ones your are using. Skip Bolnick,

I had an old X Brace HDX589 that had a removable X Brace section for rotor
placement which allowed easy installation of the Orion 2800 or about anything
else. Installation of the Orion 2800 in my much newer W Brace HDX589 was
difficult (but doable) even on the ground with the tower tipped over. Turns a
DB36 on a tilt plate with an 80/160 inverted vee.
