Incorrect Size Staple Correct Size Staple
When stapling the Z-AC Door bottom to the panel, staples
should be inserted between the Rigid Ramp and Flex
Fins. Staples should be aimed away from the kerf slots in
the bottom of the panel to prevent cracking of the door
bottom, or damage to the kerfs.
The insertion of staples at an angle or in the wrong
location will result in damage to the Door Bottom.
Only 1/2" crown staples should be used to secure the door bottom
to the panel. The use of staples with a shorter crown such as
crown 1/4"staples will result in cracking and damage to the Door
Bottom.
