Used on Airstream windows from 1975 to 1979, these flat push arm assemblies came in either 14" or 17" length and also in either a right hand or left hand model. They are made of chrome plated steel and include the plastic slider riveted in the tip.
All are obsolete. We have a small number of New Old Stock that were stored for years on a a dealer shelf and are dirty and have superficial rust. They are perfectly functional.
The left or right hand determination is made by standing outside the trailer looking at the window. The versions pictured are both right hand models, one of each size.
