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 versions pictured are both right hand models, one of each size.
