Hey there, I am working on the translation of some training products about how to install a garage door opener. However, I've come across a term I'm not familiar with, and therefore, cannot translate.
"Place a 1x4 on top of the door section".
In more specific terms, what does a 1x4 refer to? If it's a measure of some kind, of what, exactly?
