Q&A
Q: What is the Bison Zip Crank Wall Mounted Basketball Goal Height Adjuster (BA980F)?
A: The BA980F is a wall-mounted, crank-operated height adjustment system designed to retrofit basketball backboards, allowing smooth and precise rim height changes from 10 feet down to 8 feet.
Q: What mounting size does the BA980F support?
A: It is designed for systems with a 20" x 35" mounting pattern and works with fan-shaped and compatible backboards.
Q: How does the height adjustment work?
A: A hand crank (or optional electric/corded system) moves the backboard assembly along steel guide rods for smooth, controlled height adjustment.
Q: What height range does it support?
A: It provides infinite adjustment between official 10-foot regulation height and 8-foot youth height.
Q: Does it affect backboard stability?
A: No. The system is engineered to maintain structural rigidity by using dual chrome-plated guide rods and reinforced bushings to reduce flex during play.
Q: Is installation permanent or retrofit?
A: It is a retrofit system installed between the backboard and existing support structure, making it ideal for upgrading existing wall-mounted courts
Maintenance Tips
- Regularly inspect the crank mechanism, ACME screw, and guide rods for dust buildup, rust, or binding.
- Lubricate moving parts (crank, bushings, and threaded rod) periodically with a light machine oil to ensure smooth height adjustment.
- Check all mounting bolts between wall structure, adjuster frame, and backboard for tightness before play.
- Keep the adjustment tracks clean and free of debris to prevent sticking or uneven movement.
- Do not force the crank if resistance is high—stop and inspect for misalignment or obstruction.
- Ensure the wall structure remains stable and load-bearing integrity is intact, especially in outdoor installations.
- Inspect indicator labels and adjustment markings for visibility and wear; replace if damaged.
-
Protect the system from prolonged moisture exposure to reduce corrosion risk on steel components.
