The openers on my 1960 trailer wont open the window – the handle just spins. What is wrong, and what can I do?
Crank openers (operators) first appeared in 1955, and the Hehr style of opener lasted until 1965. It was patterned after casement window openers, but had a weak link. The gears were cast from soft pot metal, and by turning the wrong way with the window closed, or opened against a resistance, are easy to strip the teeth off the gears. Some small companies are looking into rebuilding them, so keep your old ones. In the mean time, replacement is the only option, and generic replacements are available from RV dealers/suppliers and manufacturers such as BlaineWindow.com.
