Whats a purling?

["Jim Dincau" <jdincau@qnet.com>]

Hi all,
In the July issue of Circle Track magazine there is an article on building a
trailer. It calls for 8 inch purlings to make the runners that the car sits
on. What the heck is a "purling"?
Jim in Palmdale, who recognizes beckon and aches but not purlings
