The gentleman that sells what you want is named Bill Steele from Nebraska.
Application: The kit is compatible with most travel trailers and fifth wheels. If the standard handle will not fit, I will supply you with a handle that will fit at no additional charge to you. If your sliding panel is a flat piece of plastic, please contact me before ordering. Will not fit doors on trailer road side.
The pictures show the standard handle mounted on a Philips slider panel with a one inch offset.
Price: $15 plus $4 S&H. I will ship multiple units for the same shipping charge.
