PERMANENT FENCE STABILITY WITH PORTABLE FENCE FLEXIBILITY

ANCHORED FOR ALL-SEASON PLAY

Poles anchor directly into natural turf to create a secure, professional outfield boundary that stays taut through wind, weather, and hard play. Choose standard 10-foot pole spacing or upgrade to 5-foot spacing for a tighter fence line with reduced sag.

QUICK-CHANGE SOCKET SYSTEM

Add the optional ground socket kit to transform your temporary fencing into a quick-change system. Once sockets are installed, your crew can remove and reinstall the entire fence in minutes for mowing, field events, or multi-sport transitions. Socket caps protect against dirt and debris when the fence is stored, so reinstallation is always clean and fast.

ADJUSTABLE FOR EVERY LEVEL OF PLAY

Add or remove fence sections to set any home run distance from Little League to adult regulation. Design your layout with intentional overlaps or gaps between sections for easy ball retrieval during games and practices.

DIRECT FROM THE MANUFACTURER

Grand Slam Fencing is manufactured by CoverSports, a company with nearly 150 years of experience protecting athletic surfaces for schools, parks, and professional organizations. When you buy direct, you get factory pricing, custom configurations, and dedicated support from the people who actually build your fence.

Common field designs using our standard length kits.

To calculate the fencing needed for foul-pole to foul-pole, multiply the home run distance by 1.57. (200′ home run distance x 1.57 = 314′ of fencing)

For 300′ home run distance (baseball) you can use 500′ of fencing. Recommended kits:

  • 2 each 150′ fence kits
  • 2 each 100′ fence kits
  • Extra fencing allows for extension beyond
    foul line or overlap
grandslam-300

For 200′ home run distance (softball & Little League) you need a minimum 314′ of fencing. Recommended kits:

  • 1 each 150′ fence kits
  • 2 each 100′ fence kits
    Extra fencing allows for extension beyond
    foul line or overlap.

Loops

With loops, temporary fence netting clips into poles on top and bottom. This method results in a secure attachment and a clean aesthetic, at the cost of additional setup effort. Once installed, fence poles do not need to be removed from the netting to store. The full temporary baseball fence can be rolled up together into a compact and manageable bundle.

Pockets

Pockets make installation of our Grand Slam Fencing™ a breeze, with the netting pockets slipping quickly and easily over poles. Pockets are just as convenient as loops long term, as you can leave poles installed when storing the temporary fencing in the off-season. The robust vinyl used in these pockets does not sag or bunch up, so the fence will look clean and tidy with this attachment option.
