Initial Standard Height Adjustment
NOTE:
The Bison Centerline systems have been designed to “set and play”, after initial set-up all net height guess
work is eliminated. The inner pole has machined marks provided for men's, women's and junior’s official
height. The outer pole has an adjustable bottom foot factory pre-set for 10” floor sockets. Please read and
follow the instructions carefully to make fine tuning adjustments if needed.
NOTE:
Tie a loop knot on both ends of the top rope of the volleyball net as needed for installation.
1. Set Standards (A) into Floor Sockets (D). Raise the inner pole of the Standard (A) to either the men's,
women's or junior’s height marks on the poles using the EZ net height adjustment crank. This line should
be just visible above the top of the outer pole. See Figure 1.
2. Lay the net out finding the end with the factory installed rope ratchet device on the bottom rope. Install the
opposite end of the net to the non-winch standard by running the top rope over the rope guide and attaching
the loop to the factory installed Attachment Screw (I). Then attach the other end of the net to the winch
standard by running the top rope over the rope guide and connect it to the 2” winch strap using the
Carabineer (K). See Figures 1 & 2.

3. Install one of the Nylon Net Collars (J) to each Standard (A) approximately 2” - 3” below the bottom of
the net. Attach the Rope Ratchet (N) on the winch end to the D-ring on the collar and attach the other end
of the bottom rope to the D-ring using one of the Carabineers (K). See Figure 2.
4. Turn the winch handle tightening the top rope of the system to eliminate the slack in the rope. Center the
net between the two Standards (A). Finish tightening the top rope using the Winch (H) and pull the loose
end of the bottom rope through the Rope Ratchet (N) to tighten the bottom rope. See Figure 3.
5. Install the Rope Ratchets (N) by running the rope through the small holes in the sides of the VB1250K Net
(F) and around the Standard (A) connecting them to the Rope Ratchet (N) and then tighten all four Rope
Ratchets (N) evenly to achieve desired net tension and maintain proper VB1250K Net (F) placement
between the Standards (A). See Figure 2.

6. Measure the net height in the center of the net to the floor. If your Standards (A) are set to junior height it
should measure 7’ (84”). Set to women’s height it should measure 7’4-1/8” (88 1/8”) and if your
Standards (A) are set to men’s height it should measure 7’11-5/8” (95 5/8”). If your measurement is
different please write it down and proceed to the next step. If your measurement is correct than you are
ready to play.
7. If not at the correct height, compute how much too high or too low, loosen the net on Standards (A) and
proceed to step #8.
8. Loosen set screw in the collar of the bottom adjustable foot with the 1/8” Allen Wrench (O). Turning the
adjustable foot clockwise will lower net height, counter-clockwise will raise net height. Each revolution
of the adjustable foot will raise or lower pole by approximately 3/16”. Make sure you use full
revolutions, the set screw must mate with the machined flat on the adjustable foot to eliminate screw
damage. Tighten set screw. See Figure 2.
9. It is advised to repeat steps 1-7 at this time. If your adjustments were correct you are ready to play.
Repeat instructions #7-#8 if further adjustment is needed.
10. Once you have set the adjustable foot you can raise and lower the VB1250K Net (F) under tension using
the EZ net height adjustment crank. VB1000 Systems is designed to allow minor net height adjustment
without removing tension from the net. Do no attempt to raise the net more than 1/2" or lower the net
more than 1" without reducing the net tension. One full revolution equals approximately 1/16".
Additionally you can make slight modifications to fine tune the net height by raising and lowering the
collars, by tightening/loosening the winch, and by adjusting the tension on the side rope ratchets if
necessary. See Figure 3.
11. When you are confident that the initial net setup is complete trim excess top and bottom rope as desired.
Burn ends with a lighter to eliminate fraying.
NOTE:
Excessive tightening of top rope is not necessary. Crank the winch until poles start to flex. Further
tensioning results in lowering of the top rope. Achieve proper height using the inner pole adjustment and to
achieve proper net tensioning use the rope ratchets.

1. Loosen top net cable. Use the net height adjustment crank to adjust the inner poles to the desired height
indicated by the height markings machined on the inner poles See Figures 1and 3.
2. Adjust Nylon Net Collars (J) so that they are 2”-3” below the bottom of the net. Crank top rope tight with
the Winch (H), then pull bottom rope tight through the Rope Ratchet (N). Reattach Rope Ratchets (N),
center the net between poles as in previous instructions and apply desired tension. See Figures 2 and 3.

NOTE:
Excessive tightening of top rope is not necessary. Crank the winch until poles start to flex. Further tensioning
results in lowering of the top rope. Achieve proper height using the inner pole adjustment and to achieve proper
net tensioning use the rope ratchets.
Both Nets the Same Height
1. Remove tension from both nets with the Winches (H).
2. Adjust all three poles by cranking the net height adjustment crank to the desired height. See Figure 4.
3. Tighten both nets using the Winches (H), retighten bottom ropes and reinstall and tighten Rope Ratchet (N)
See Figure 4.

Nets at Different Heights
1. Remove tension from both nets with the Winches (H).
2. Attach one of the Nylon Net Collars (J) provided in the hardware kits to the center standard towards the top
See Figure 5.
3. Adjust the net that will be at the greater height using the net height adjustment crank, then retighten those
two poles. See Figure 5.
4. Adjust the Nylon Net Collar (J) on the center pole to the desired height for the second court and tighten.
5. Adjust the lower net court winch pole and tighten the Winch (H). See Figure 5.
6. Reattach and tension both bottom ropes.
7. Attach all Rope Ratchets (N) per previous instructions.
8. On multiple side by side court systems, the Winch (H) on the court adder poles should be placed above the
collars so web strap will not interfere with bottom rope attachment.
