The different fits are labeled with a one or two letter designation. In
addition, a general description of each follows along with the more familiar
breed-specific or back-type classification. These limited descriptions cannot
be readily utilized for fit determination but will assist when comparing one to
J - Semi-Quarter Horse (Semi)/Arabian (Arab) - Steeper front and rear rafter
angle and closer-spaced bars relative to Standard Quarter Horse fit when
positioned at standard spread. In addition, sufficient bow (rocker) enables
this fit to conform well to the short Arabian back having a narrow wither
dropping off quickly to the shoulder.
D - Standard Quarter Horse (SQ) - Approximate 92º front rafter angle. Good
front flare, bow and upturned tails to avoid bridging and bar edge pressure
TF - Full Quarter Spread (FQ) - Same bow (rocker) and wind (twist) as 'D' fit
with an additional 1/2” front spread ('GW+1/2' or '+1/2') than standard.
NE - Straight-Back Quarter (SBQ) - Similar flare and rafter angle to the 'D' fit
with much less bow. Developed for straighter backed, well collected horses.
Also works well for mules that require a flatter front rafter than the 'SE'.
SE - Mule (Mule) - Reduced bow and steeper front rafter angle to conform to
the distinctive mule back. Helps prevent the back of the saddle rocking up
when cinched, which creates tremendous pressure under the stirrup leather
when the rider's weight pushes it back down.
HA - Draft Horse (DH) - Approximate 105º front rafter angle. Flatter rear
rafter also and less bow for broad, flat backs with little dip.
LT - Gaited Horse (GT) - Steeper rear rafter angle, additional front flare and
more bow relative to the 'D' fit.
PW - Walking Horse (WH) - Similar to LT with steeper front rafter angle.
AW- Full Wither (FW)/Arabian (Arab) - Flared out front and rear to allow for
full or mutton wither with no pockets. The resulting bow enables this fit to
conform well to the short Arabian back having wide withers rounding out into
the shoulder. The AW has also been found to work for more dipped-back
X- (Fit Form not yet available) Performance Quarter (PQ) - Flatter front and
rear rafter angle and less convex front bar pads allow for the broad wither and
well-developed shoulder muscles of the highly trained, daily ridden working
quarter horse. A more open waist facilitates collecting and core development.
