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 either aluminum or chrome plated steel. They include a solid 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 surface pitting, oxidation, or rust. While they may not look perfect, they are perfectly functional with all plastic sliders in excellent condition.
The left or right hand determination is made by standing outside the trailer looking at the window. The versions pictured are both left hand models, one of each size.
