ROOF-TOP ATTACHMENTS
The photo below shows our standard roof-top attchments, spot welded to a belt. They can also be made with a square or a rounded top.
Attachments are typically only welded to stainless steel belts, but we can weld them to high carbon steel belts.
Keystone does not recommend these attachments taller than 2 inches above the belt, although the higher the attachment, the more likely they are to bend.
