Pro-Lok EWL-111-B – Frequently Asked Questions
1) Will the Pro-Lok keyed sash lock work on vinyl and aluminum windows, or only wood?
It works on all three. The Pro-Lok keyed window sash lock is rated for wood, aluminum, and vinyl double hung windows, so you can standardize across a building with mixed window types instead of stocking two different locks.
2) Does installing this window lock require drilling through the glass?
No glass work at all. The Pro-Lok keyed sash lock mounts to the bottom and top window sashes and secures the window with a cam action latch, so the installation stays entirely in the sash frame. That is what makes it usable on units you cannot risk breaking or replacing.
3) Is this window lock only for double hung windows?
Yes. The lock is specified for double hung windows, where the top and bottom sashes meet and the cam draws them together. Sliders, casements, and awning windows move on a different axis and this style will not engage properly on them.
4) Do keys come with the Pro-Lok wood sash window lock or do I order them separately?
Two keys ship with each lock. Nothing extra to order for basic operation. If you are doing a multi-unit property and want a single key across every window, plan that out before you order rather than assuming units arrive keyed alike.
5) Is this window lock strong enough for commercial or apartment use, or is it a residential product?
Pro-Lok lists it for residential, commercial, and industrial use, and the body is diecast rather than stamped. That covers rental units, offices, and light industrial openings where you need a keyed window that a tenant or occupant cannot simply flip open.
6) How does this keyed sash lock operate day to day compared to a standard cam sash lock?
Operation is a two-step: press the lever to close the cam, then turn the key to lock it in position. A standard cam sash lock stops at the lever, which anyone inside can reverse. The key step is what makes this useful for ground floor and fire escape windows where you want the window held shut against someone reaching in through a broken pane or an unsupervised occupant opening it.
7) What finish does the Pro-Lok keyed window sash lock come in?
Brass is the finish offered, and it is the only one. If you are matching existing window hardware on an older wood sash building, brass usually blends with the original lifts and sash locks already in place.
