Space Balls™ is a patented product which has the ability to:

1. Automatically center panels in the assembling process.
2. Expand and contract as the panel does.
3. Eliminate panel rattle and help to eliminate the cracking of glue joints.

 8 – 10 Space Balls are recommended per door. Space Balls should fit snug, but not tight, by compressing one-third the diameter of the ball.
