What are cam locks and ventilation locks?
Cam locks are used to tighten sashes and reduce drafts. But more importantly, they improve security. A Good window will have two locks when the width is 25″ or more. Window manufacturers who cut corners use two locks only when the window reaches 32″ or more in width. We provide two locks on windows over 25″ wide for double-hungs and sliding windows. Ventilation-limit locks are stops in the sash, which permit windows to be opened partially while retaining security. This is another standard feature of our windows. Not all window manufacturers provide ventilation-limit locks.
