These sleeves are set in the playing surface so Jaypro uprights can be installed and removed easily without disturbing the footing. The 3.57 in. inside diameter accommodates systems measuring up to 3.5 in. in diameter, and the 21.125 in. sleeve length with a 3.875 in. outside diameter gives the footing enough embedment to hold the post square.
Each pair arrives complete: two OBV ground sleeves (OBV-100G-2), two 1/2 in.-13 x 4.5 in. hex cap screws, two 1/2 in.-13 jam nuts, two locking ground sleeve caps (AF1213A) and two vinyl sleeve caps (RP717). The stop bolts set the post depth and the caps close the sleeve when the uprights are stored.
Jaypro's footing details show concrete for sand filled playing surfaces and concrete, crushed stone or blocking for grass, clay or asphalt. Note that standard sleeves do not include contamination prevention, so the user must keep sand from packing inside the sleeve during use, and the spec sheet should not be treated as the installation reference.
