Pro-Lok EWL-120-AL – Frequently Asked Questions
1) Will the Pro-Lok lever window lock work on a vertical hung window, or is it only for sliders?
It's built for horizontal sliding windows. The lock clamps onto the window track, so it needs a track to grip. A double hung or casement window has no slider track for it to mount to, and this is the wrong part for those openings.
2) Can I set a slider window to stay open a few inches for ventilation and still lock it?
Yes, that's the point of the lever design. You slide the lock along the track to wherever you want the sash to stop, then press the lever down to cam it tight. Set it against a closed sash for full security, or back it off a few inches to leave the window cracked for air and still block it from being pushed open further.
3) Does installing the Pro-Lok window lever lock require drilling into the window frame?
No drilling or fasteners. The lock mounts onto the bottom or top of the window track and you press the lever to tighten it in place with cam action. That makes it usable on rental units and storefront glass where you don't want to put holes in the frame, and it comes back off without leaving damage.
4) Is this window lock suitable for an apartment building or commercial property, or is it a residential-grade item?
Pro-Lok lists it for residential, commercial and industrial use. The body is heavy-duty aluminum, and since it needs no drilling, a property manager can standardize it across a lot of units quickly and pull it when a tenant turns over.
5) Can the Pro-Lok lever lock be used on an exterior window, or will the weather get to it?
It's rated for both interior and exterior windows, and the body is aluminum rather than plated steel, so it isn't going to rust out on a sliding patio or exterior sash.
6) Does the top of the track work as well as the bottom for mounting this lock?
Either works. Pro-Lok states the lever lock mounts to the bottom or top of the window track, so if the lower track is fouled with a screen channel or debris, you can run it in the upper track instead.
7) What finish does the Pro-Lok lever window lock come in?
Aluminum is the only option, which is the raw material finish rather than a plated coating. If you're matching a bronze or white vinyl window frame, expect a silver-tone lock sitting in the track.
