Jaypro Sports PVB-75S - Manual (Page 9)

Using the proper material to pour the sleeve in place is essential to a good installation.
Several brands of hydraulic cement are available, however, some set too fast to work
with. DO NOT USE concrete or similar materials. Hydraulic cement must be used to
prevent hair- line cracks from forming. Rockite works quite well, it provides 15 minutes
of working time, 30 minutes to set-up. The material is more expensive than some, but
consistency and quality are priceless. Mix enough material to fill the hole completely,
usually ¾ of a 5 gallon bucket of mixed material is sufficient. Be sure to mix the material
as directed by the manufacturer. Pour the material into the prepared hole until it nears the
bottom of the slab. Insert the sleeve to check the level and adjust until it will finish within
1” of the top of the slab. Some floors have a gap between the slab and wood flooring,
making this less critical. Insert screws into the top outer ring and tighten to the floor.
Carefully lower a standard into the sleeve to check level, this can be use to pry the sleeve
gently into position. It is best to have the standard SLIGHTLY leaning away from the
direction of pull, or away from the court. Remove the standard and proceed to next
sleeve. After the hydraulic cement has set, remove the top plate from the sleeve, and
replace the top plate.
