Patent  U.S. # 5317853 / CAN. # 2115722

Insertion Procedure:

 For 5mm Spaceballs

 

Spaceballs need a minimum spacing of  3mm per side.  If you cut your stiles and

crossers, as you would normally do for your panel doors......then cut your panels

3mm smaller on all sides.  This will leave the minimum space for proper

installation and the Spaceballs will be able to expand and contract as needed.

 

 

 Please Note: If you are using a curved bottom dado slot this spacing

must be increased to a minimum of  4mm on all sides

 

 

We recommend 2 balls per side ( possibly 3 if the door is very tall or wide).   The

Spaceballs will be compressed when the door is assembled and will expand and

compress with the movement of the wood.  

 

 

It is advisable to keep the humidity

content of the wood under consideration when constructing your doors.
