ProwLock – Overview


About Prowlock


There are window security products available that protect closed windows, but do not effectively secure an open window for ventilation or safeguard from falling incidents and break-ins.

Our innovative product – ProwLock – protects open  windows with patented design elements that secure to the window, frame and channel without screws. This superior design provides child-safety by restricting the window opening and has tamper-proof features to prevent dislodging or prying from the outside.

ProwLock  is just right for vinyl, or wood-frame  basement, ground-floor, and upper-floor windows in any orientation: slider or hung. 

ProwLock is ideal for walk-out basement, main floor  and especially for upper –floor patio doors to balconies in apartments and multi-family and hi-rise buildings. 

ProwLock is available in two models – your Window Models to secure slider and hung windows, and your Patio Model suitable for standard patio doors.

ProwLock Models are  adjustable for most any window and patio door size, and is simply installed, without tools.

ProwLock is easily removed for window/frame cleaning and has a  quick release mechanism for removal in an emergency
