Product guide
Why choose this round pen?
Ships as numbered panels with chain-and-pin connectors, so the circle you set is the circle you keep. No concrete, no post holes, and nothing bolted to work loose. You can move the whole pen when the drainage tells you to.
Key listed specifications for this product are diameter 40 ft, 5-rail layout, steel 14 gauge. Use the full specification section to confirm the complete configuration.
Count 10-ft panels and pick a diameter before you order a circle. 40, 50, and 60 ft are the same decision.
Planning the 40ft Round Pen 5-Rail
Confirm the diameter, rail count, gate location, site clearance, and included connections before preparing the pen site.
Diameter: The listed diameter is 40 ft. Measure the complete installation and allow for adjacent components, access, drainage, and working clearance where applicable.
Rails: This configuration uses a 5-rail layout. Match the openings to the animals and the way the enclosure will be used.
Steel: The listed steel is 14 gauge. Use this specification when comparing strength, compatibility, and like-for-like alternatives.
Options: Color options are available for this product. Review the selections and confirm the final configuration before ordering.
Warranty: This welded product carries Blacktail's lifetime warranty on welds, frame, and joint integrity.
40 ft
Best fit for groundwork on foot, close handling, and a settled horse that does not need a wide ridden circle.
Best fit for: Groundwork on foot. Close handling. A settled horse that does not need a wide ridden circle.
Choose it when: The main work stays on the ground. You want the horse close. The site is tight and 40 ft across the center, plus gate clearance, is what you actually have.
Not the first choice when: You plan to ride in it regularly. A canter in 40 ft is tight. The horse leans through the turn the whole way around. That is shop-floor / field feedback, not a score.
Confirm before ordering: Measure 40 ft across the center, not around the outside. Pick 4-rail or 5-rail. Plan footing yourself. The kit does not include it.
Published on those SKUs: twelve 10 ft by 5 ft panels, one 4.5 ft bow gate with an EZ-latch, 26 panel clamps. No concrete. No post holes.
