Blacktail Corrals Updated September 12, 2026

Complete welded steel riding arena perimeter

Choose an arena footprint around the way you ride, the available ground and the space needed outside the fence. Blacktail lists perimeter kits in 80x120, 120x200 and 140x240 sizes.

The kit supplies the arena perimeter. Ground preparation, base and riding surface are separate parts of the project.

80x120: the smaller footprint

An 80x120 arena covers 9,600 square feet inside its rectangular footprint. It is the smallest standard arena size in the range.

Stake the perimeter and walk the planned exercises before ordering. Include room outside the arena for access and maintenance.

120x200: more working room

A 120x200 arena covers 24,000 square feet. Four-rail and five-rail perimeter kits are available.

Consider how the added length and width affect the riding space, drainage, footing quantities and maintenance access.

140x240: the largest standard layout

A 140x240 arena covers 33,600 square feet. Compare the full project area, not just the fence dimensions, when setting out this layout.

Check the space needed for turning equipment, moving horses and maintaining the surface around the gates.

Gates and custom layouts

The arena packages include drive and walk gates. Confirm the quantity, clear opening widths and locations for the selected kit.

Ask about a custom footprint when the standard sizes do not fit the ground. If the project is a circular training pen, compare the separate round-pen kits.

Finish the ground plan first

Mark the full perimeter, corners and gate positions. Discuss the intended riding use and site preparation with the people designing and maintaining the arena.

Complete the grading, drainage and surface plan before the perimeter arrives. Confirm unloading arrangements, connections and all included components with the order.
