Abstract
A ladder rail cap comprising a shell. The shell has an inside surface defining a chamber into which a ladder rail is disposed. The shell has a top end and a bottom end having an opening in communication with the chamber. The ladder rail cap is also comprised of a clip attached to the inner surface of the shell near the top end of the shell. The clip mates with an end cap of the ladder rail and penetrates the ladder rail's envelope to hold the shell onto the rail. The present invention pertains to a ladder. The ladder comprises a first side rail having an end cap and defining a rail envelope. The ladder is also comprised of a second side rail having an end cap adjacent and in parallel to the first side rail. The second side rail defines a rail envelope. The ladder also comprises at least a first rung connected to the first side rail and the second side rail. Additionally, the ladder comprises a ladder rail cap disposed on each side rail. Each ladder rail cap has an inner surface defining a chamber and a clip attached to the inner surface. The end cap of each side rail is disposed in the respective chamber and mates with the respective clip of the respective cap. The present invention also pertains to a method for forming a ladder. The method comprises the steps of placing an opening of a ladder rail cap over an end cap of a ladder side rail. Then there is the step of moving the ladder rail cap onto the ladder side rail so the top of the ladder side rail is disposed in a chamber of the ladder rail cap and a clip attached to an inner surface of the ladder rail cap, which defines the chamber, mates with the end cap to hold the ladder rail cap on the ladder side rail.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
