Grand Master SR  (English/Western)

The most elite trailer in the Polyester series, the Grand Master is a striking trailer for the horse to 1.82m/18 hands. The longer, wider rounded hot-dipped galvanized steel chassis than the Big Master, with the World Class WCF suspension provides a larger trailer with the ultimate smooth ride.  The rounded chassis front in the SR model affords a full height storage cupboard on the left side of the trailer. Access to this cupboard is from both inside the trailer and outside the trailer on the Driver’s side. Everyone likes a little bling- with Alloy wheels and the black inset for the double windows – the Grand Master SR makes a statement as you arrive!  Add some colour or a decor to the many extras for both horse and rider, one can easily see why it is the top trailer for its weight class – GVWR of 2700kg/5952lbs.


What Makes the Grand Master SR Unique?

The Grand Master SR is identical to the Grand Master SKA – but offers a very different tack storage cupboard.

In general, the Grand Master SR combines the stall divider system of the Portax into the horse stall. Easy access to the horses by swinging a panel away allows you to tack a horse or to add/remove shipping boots. An air of elegance with its covered side braces and polyester fenders which can be in coordinating or contrasting colours to the roof and body- the Grand Master also has a Black Inset for the double windows.  Apply an exclusive decor by Jan Künster to tailor your trailer to you. The entire trailer sits atop the elite WCF suspension, which keeps the road chatter where it belongs- at the level of the road, not bothering your horses legs.  Added features for your horses include an additional rubber mat for wear protection against pawing or shoes with road studs and portable feed buckets that can be used in transit or at shows. A bright white, wide airy horse stall with adjustable stall bar settings and two tinted pop-out windows complete the inner stall look.

Saddle storage is accessible from both inside and outside of the trailer.
Standard is the English Version:  2 Telescopic adjustable saddle racks for English Saddles, 4 shelves, many hooks, broom with telescopic handle, shovel, mirrors and net on each door, 2 sets of crop/whip holders and 2 sizes of stools. A third English rack is possible to add for Eventers as an Accessory.

The Grand Master has a rounded galvanized steel chassis frame. The steel chassis secures the aluminum floor panels. Under the floor, there are longitudinal bars as well as cross-member pieces to provide the greatest strength.


The Grand Master SR for has two 33” wide stalls + 7’6” internal height. The saddle chest sits in the wide nose of the trailer. Two tinted sliding windows on each side wall of the trailer allow air to flow into the trailer. Roof Vent for added air flow and temperature control. A hay ring centered in the roof and a bracket on top of the saddle chest offer different positions to tether hay bags or hay nets. A full height storage cupboard makes packing for a show extra convenient. Rings for trailer ties are found at the level of the chest bar. This allows the horses to lower their heads for balance and clear their sinuses. Two portable feed buckets and additional rubber mat under the front feet make a cozy space for your horses.
