The outstanding qualities of the original Equal-i-zer Sway Control Hitch are being enjoyed by owners of all types of trailers. The Equal-i-zer hitch works with travel trailers, boat trailers, trailers with surge brakes, utility trailers, horse trailers, cargo haulers, pole (or single) tongue and many other trailer types. Owners that have a single or pole tongue are often left out of weight distribution options due to problems with fitting, but that can now be easily solved by using the Equal-i-zer Pole Tongue Adaptor.
