High Country Plastics makes poly mounting blocks for horse owners in two heights: the MS-22 Three Step Mounting Block at 22 inches and the MS-19 Two Step Mounting Block at 19 inches. Both have a wide, sturdy base, a carrying handle and a lifetime warranty, and both are light enough for kids to move around the barn.

How Can a Mounting Block Help You?

A mounting block puts the stirrup at a comfortable height, so you step across into the saddle instead of hauling yourself up from the ground. That matters on a tall horse, for a short rider, for a child, and for anyone whose knees or hips have opinions about the morning. You get on with less effort, land in the saddle more quietly, and start the ride balanced.

From the barn to the pasture, in your home and your garage, High Country Steps are useful for multiple tasks, says High Country Plastics. Use one to safely mount or groom your horse, to step in and out of your trailer or RV with ease, and to reach the hard to reach items on the top shelf of the tack room.

How Do Mounting Blocks Help Your Horse Avoid Back Soreness?

When you mount from the ground, all of your weight hangs off one stirrup while you swing up. That pulls the saddle toward you and presses the tree into the near side of the withers and back, and it happens every single time you get on. Over months of riding, that repeated twist is hard on the horse and it also shifts the saddle off center.

Starting from a block shortens the climb. Less of your weight swings from the stirrup, the saddle stays straighter, and you sit down gently instead of landing hard. This is why many riding instructors and saddle fitters ask riders to use a mounting block whenever one is available, and why it makes sense to keep one at the barn and another with the trailer.

Which High Country Mounting Block Is Right for You?

Both blocks share the same design. All steps feature a convenient carrying handle and window cut out for storage, and both are built from durable light weight poly construction. The difference is height and size, so choose by your horse, your rider and where the block will live.

  • MS-22 Three Step Mounting Block: a 22 inch overall height on a wide, sturdy base, 31.25 inches by 18 inches by 22.5 inches, and at only 25 pounds light enough for kids to move around.
  • MS-19 Two Step Mounting Block: a 19 inch overall height on a wide, sturdy base, 26 inches by 15 inches by 19 inches, and light enough for kids to move around.
  • Both models: a carrying handle, a window cut out for storage, durable light weight poly construction and a life time warranty.

The three step suits taller horses and riders who want the most help getting on. The two step is the smaller, lighter choice to carry to the arena gate or keep beside the trailer door.

Are High Country Mounting Blocks Really Built to Last?

Yes. High Country Plastics builds its mounting blocks from durable light weight poly, and each model carries a life time warranty against manufacturer's defects. The company describes its built-to-last products as known for their durability, quality, strength, innovation and warranty, and the mounting blocks carry the Made in U.S.A. mark on their product pages.

Poly is a practical material for a block that lives by the arena gate or rides along to shows: unlike a wooden block it will not rot or splinter, and it hoses clean.

Bob Pruitt, publisher of InfoHorse, has personally owned High Country Plastics products for many years, and in his words, they hold up very well.

What Colors Do the Mounting Blocks Come In?

Both the three step and the two step come in seven colors: Black, Blue, Forest Green, Pink, Purple, Red and Tan. Riders often match a block to their barn colors or their show colors, and a bright color is easy to spot in a crowded trailer or at the end of a long aisle.

The Solution Section (FAQ)
What is a mounting block for horses used for?

A mounting block is a sturdy step a rider stands on to get into the saddle, so the stirrup is at a comfortable height instead of hip height. It makes mounting easier for children, shorter riders and anyone with stiff knees or hips. Many riders also use one for grooming, braiding and tacking up a tall horse. High Country Plastics says its steps are useful from the barn to the pasture, in the home and in the garage.

Does using a mounting block help prevent back soreness in horses?

Mounting from a block reduces the strain on your horse's back each time you get on. From the ground, your full weight hangs off one stirrup and pulls the saddle against the near side of the withers. A block shortens that climb, keeps the saddle straighter and lets you sit down gently. That is why many instructors and saddle fitters ask riders to use one whenever it is available.

Should I buy a two step or a three step mounting block?

Choose the three step for taller horses or riders who want the most help, and the two step for a lighter block that is easy to carry. The High Country Plastics MS-22 Three Step stands 22 inches tall and weighs 25 pounds. The MS-19 Two Step stands 19 inches tall and is smaller and lighter. Both have a wide, sturdy base and a carrying handle.

How big and how heavy are High Country Plastics mounting blocks?

The MS-22 Three Step Mounting Block measures 31.25 by 18 by 22.5 inches with a 22 inch overall height and weighs 25 pounds. The MS-19 Two Step Mounting Block measures 26 by 15 by 19 inches with a 19 inch overall height. High Country Plastics says both are light enough for kids to move around. Each has a carrying handle and a window cut out for storage.

What warranty comes with a High Country Plastics mounting block?
